After the Germans had been held at the Marne in 1918 it was all over for them.

The scale of casualties gives an idea of the relative involvements of various nationalities,  
German 168000  
French…95000  
British…13000  
American…12000

So although the US was in there, they represent less than 10% of the fatalities, but of course their contribution tied up enough Germans to make their operation fail.

The Germans had targeted the French armies as they had thought these were most likely to break, there had been mutinies etc but this completely misunderstood the French mentality, they were not protesting so much about the war itself as the useless tactics, their will to fight was every bit as strong as ever and Germany found this out at a high price.

There can be no doubt that the French would have been willing to fight for far longer, they were completely committed to freeing their country, a longer war would have utterly bled Germany white.

US forces decisive, well no, but significant, it is still most likely that Germany would have failed in their attempt to reach Paris, but I would say that the obvious reality that the US was going to become far more involved was the single most decisive factor in Germany deciding to surrender when it did.

The Germans had overextended and overexpended themselves, along with this the British had developed (mainly the Canadians and Australians) the rolling barrage, co-ordinated use of tanks, and aircraft in what was in reality the Blitzkrieg style of warfare.

This was demonstrated very effectively in what General Ludendorff descirbed as ‘Germany’s blackest day’ during the battle of Amiens, which started even as the Germans were being held and pushed back at the Marne.

The forces involved were largely British, Australian, and Canadian although there were some regiments of the US 33rd division involved.  
The British army at the time was recognised as the best trained and most efficient killing machine of any army including the Germans on the Western front, but then it should have been, given the horrific way it had to learn its trade at the Some and Passchendeale.

My view is that the US contribution was not hugely significant militarily but that it showed the Germans the massive potential that was there, the mere fact of US troops being present at all was the greatest contribution, this is what was decisive.

There is a view that the blockade of Germany by the Western allies imposed a timetable upon Germany, put simply, if Germany had not won the war within a certain timeframe, lack of resources would mean that they would almost certainly lose, and this is why they were much the more aggressive toward the last months of the war.

Now put yourself in the heads of Allies leaders, they must have been aware of what the effect of blockading Germany was, and they must have been aware that time was on their side, as Germany grew weaker, the Allies tended to grow stronger, and militarily they became better armies

There is no reason at all to suppose that the Allies would have been prepared to come to an armistice that was favourable to Germany, the French, quite frankly, wanted to annihilate Germany, they were the ones who wanted to destroy Germany completely, and it was Wilson who held them in check.

If Wilson had not been there as a moderating voice I would have expected that France would have exacted a far higher price on Germany, larger parts of the country would have been occupied, and the country would have been broken up into its pre-1870 elements.

This position takes for granted that even without US support there would have been a war ending with capitulation by the Central Powers rather than a negotiated armistice by powers still standing on the field.

Do you truly believe that this would have happened without the US?

As my previous post would indicate I think that this was specifically what the US brought to the table; a sledgehammer that was big enough for Ludendorff to just throw in the towel rather than be struck by it.

No mention was made about there not being US support, but that is quite differant to actual entry into combat.

Without US material support the Germans would have been in a far better position.

The presence of US troops was decisive in that it ended the war, but it would not have changed the result, their presence was mainly a sideline when compared to the numbers already committed.

Had the US not been there on the battlefield then Germany would have fought longer, and been completely destroyed, the British army was suprerior to all other combat troops on the front at the time, and by quite a margin, the French were perhaps even more determined to destroy

It would not have been pretty, and the US would have been even more pre-eminent after the war as Europe would have been more devastated.

I think that the US presence was a major factor in what happened at Versailles. The other Europeans, emboldened by the surrender, treated Germany as a total loser unworthy of respect, and gave them a treaty whose terms devastated Germany probably as much as the war did.

By support I understand more than material, that is to say a political commitment to conflict.

I do see your point and I agree that had the war dragged on for much longer the Germans would have both lost and been crushed.

I’m taking a position between the two though, where the US is not politically in the war and the German Left after a disappointing early autumn 1918 have gained enough power to propose a favorable armistice to the Allies, without surrender. I can’t quite see how France would a) get Britain to support her in declining and b) enforce a Versailles style peace in that environment.

> Not quite. As Bismarck unites Germany in 1871 in the aftermath of the war with France, Russia supports Bismarck. In the years leading up to 1871 Prussia and thereby Otto as part of the ‘Deutsche Bund’ has been walking on a tightrope between Russia and Austria that now gets increasingly unstable.
> 
> By 1875 France has rearmed and war threatens again. Much to Bismarck’s dismay England and Russia intervenes on France’s side. Bismarck reacts with deep indignation, even personal anger against Chancellor Gortschakoff and Prime Minister Disraeli. Deadlocked ‘with all the bayonets of Europe facing the center, where Germany happens to be’ as Bismarck put it he sets out on a new delicate path of appeasement of France and her newfound friends.
> 
> At his summer retreat in Bad Kissingen in 1877 he formulates the plan that will eventually lead to first the coalitions that enter WWI and then to the war itself. His plan is mainly aimed at isolating France, disabling any major coalitions, and avoiding a war on the European continent at all costs. As we know in retrospect it didn’t work. lokij is kind of right in as much that it could have worked if Bismarck wouldn’t have been ousted from power in 1890, but we will never know that.
> 
> The Russo-Turkish war that breaks out later that year affords him full possibility to start acting on these plans. At the Berlin Conference of 1878 he manages to sow together something that looks like at least the beginning of a viable solution. He avoids war with France and gives Russia room to maneuver in the East, negotiates land for Austria-Hungary, while affording England assurance that Russia will not gain a too strong foothold in the Mediterranean. However, Russia is not satisfied and a strong anti-German coalition forms amongst parts of the Russian leadership.
> 
> In 1879 he feels forced to enter into coalition with Austria-Hungary. Suddenly Germany finds itself on the opposite side of Russia, and forget not that it was Russia that originally gave Bismarck the support to separate from the Austro-Hungarians. With somewhat of a magical tour de force he manages to turn Russia into an unwilling ally in this game through the triple entente agreement of 1881. Behind the back of Austria he signs a reassurance treaty with Russia that more or less negates both the previous coalitions. Here’s the rub with the whole thing; his reassurance agreement is merely an artificial way to appease Russia. As long as Bismarck stays in power he manages to keep the resulting, but delicate balance alive. When he disappears from power it all collapses and exactly what he wanted to avoid at all costs happens, an alliance between France and Russia.
> 
> Now the German-Austrian Coalition and the Franco-Russian Entente has a very sad side effect. Russia was no real enemy of Germany, but opposed to Austria-Hungary while France was at odds with Germany but not Austria-Hungary. Through the two coalitions Russia is now suddenly opposed to Germany and France to Austria-Hungary and by extension the mutual agreements of protection between England and France creates exactly the grand anti-German front that Bismarck wanted to avoid, which as we know will be the state in which Europe goes to war in 1914.
> 
> Hence one must conclude that the conflict with Russia has deeper roots than just this last bit which of course is what brings on full opposition, but still remains only the consequence of many years of brewing disagreement.That was without a doubt the German ground for support to Lenin, but one should also note that the unnatural alliance with France and the subsequent war against Germany sowed much dissent in Russia, which played a part in paving the way for rebellion.Well they did more than that. They interrupted the peace negotiations with Trotsky and renewed hostilities with Russia to eventually gain the conditions they demanded in the Brest-Litovsk Treaty. To definitely say that this would have led to continued conflict is however somewhat contentious. Russia later used the defeat of the Central Powers to declare Brest-Litovsk null and void. Would they have done that if the Central Powers had come out of the war standing on their feet? The land that Russia ceded was largely, to not say completely populated by non-Russian speaking peoples. The domestic situation in Russia was shaky at best by the end of the war, too shaky for an external conflict. Independent of that it might be they wouldn’t have needed to fight Germany for that, which I’ll get back to later on. Let’s first look at what is going on inside Germany at the same time.Not so certain. Bismarck championed social reform in Germany. He also allowed the Socialists existence, albeit a curtailed freedom in order to avoid a new revolution.
> 
> With his defeat in 1890 there was a swing back to conservatism. The Socialists evolved at this time from their revolutionary base and became a mainstream movement. However, in 1914 the SPD were still locked out from power and strongly curtailed in their freedoms. That year, albeit under strong internal strife the Social Democrats ended up supporting the war effort and thereby gained a certain freedom and legitimacy and much needed support in the Reichstag.
> 
> In 1916, with the war ground to a halt with staggering loss of life and rampant financial and social costs the ‘Kriegzieldebate’ or ‘War Goal Debate’ breaks out splitting German politics down the middle with a right wing advocating a full on war to more or less bring Europe under the heel, and the left wing advocating a war that ensures Germany a peace with guaranteed borders as of 1914. During this debate the Social Democrats under Ebbert muster so much support that by the end of the war they are the largest single party in Germany. A party supportive of the International and saw the Russian revolution as a part of it, hence there was a future ally in Lenin. Lenin and Trotsky on their side had already stated the desire to expand the International to the West, hence there were mutual interests at hand.
> 
> The right wing spearheaded by Hindenburg and Ludendorff strengthened by emergency rule held the floor in the ‘Kriegszieldebate’ though, and the war continued. Had the left wing won this debate and managed to halt the dogs of war it is not unreasonable to speculate that the end of war would have seen a Germany emerge that was not only ready to tolerate the Soviets, but ready to ally with them. As I shall get back to, this is relevant both to the relationship to Russia as well as to the OP. Methinks lokij is mixing up Germany and Austria-Hungary a little. Look at what I have written up to here. Russia’s conflict in the East was with Austria-Hungary. The German conflict was an extension of the alliances that formed as a result of the politics of Bismarck and his successors, not German interests in the East. It is a frequent misconception that Germany had a long standing interest in lands under Russian dominion that stems out of Hitler making a big deal out of contested lands like Sudeten, you might want to consider that these were located in Austria-Hungary at the time. Let’s also remember that Brest-Litovsk was negotiated by the Austro-Hungarians with Germany supporting as an ally.Pray… Why?!? This reads like something out of ‘The Handbook on Why We Must Destroy the Hun’ or ‘The Kaiser and His Evil Plans for World Dominion’. A somewhat dated position, don’t you think? There is little in the years between 1871 and 1914 to support that Germany would have liked to engage in such politics. I think most of what I have brought up so far speaks against it as a matter of fact. It’s easy to forget that Germany before 1932 was a budding nation that pioneered democracy and social reform in Europe. The Kaiser had very littler power, if any. As a matter of fact he was rather a harmless fruit-cake sort of guy that mostly cared about his score of Pekingese dogs and what plumes to were in his hat to the Opera on Friday. Hindenburg and Ludendorff were Imperialists, without a doubt, but even they would have been appalled at the idea of a non-constitutional monarchy. More importantly, as I have already said the Socialist movement was strong, very strong as we came to see in the November Revolution of 18 and during the Weimar Republic. It’s just a pity that history had another route in plan for Germany and Europe.

The US had just entered the war and it would have been until 1919 before a significant impact from the US involvement could be felt tactically. Meanwhile the naval blockade in Skagerak is hurting Germany badly.

With the prospect of the US entering fully into the war in the next year he conceded that the Left Wing was correct and did the only reasonable thing. He acted too late though and the price the world paid for his mistake was a peace that paved the way for another war.
> 
> Had the US not been in the war it is of course impossible to say what would have happened. There is however an interesting possibility that opens up when you see it from the German Left Wing’s perspective. The Western Offensive still would have failed. The September Offensive might not have happened, but if it did it probably would have led to at the worst another stalemate and more likely a more modest Allied victory (the Allies didn’t intend it as a final offensive in the first place, but were gearing up for a final offensive in 1919). Had the September offensive happened, it probably still would have been enough to push the political balance inside Germany to the Left Wing’s advantage. However, the peace to then be negotiated would not have carried the prospect of crushing defeat in 1919 and would have been negotiated between parties that still stood at each others necks along the Marne, each with a non-involved potential ally carrying huge reserves of manpower and natural resources.

Wow, I didn’t expect a reply quite this lengthy regarding a little sentence I tacked onto the end of my reply to the Op. ;\>

My opinion about future conflict between Germany and Soviet Russia is based on the counterfactual premise that Germany WON the war with all the ramifications that entails. If Germany managed a victory in the absence of US involvement it would have been a major vindication for the conservative elements in German government. The SPD might not have made such huge gains in power and influence in the aftermath, ready as they were to capitulate and settle for 1914 borders back in 1916 when Germany still faced a war on two borders. You also suppose that German socialism and the newly arrived Bolshevik regime had much in common, I have reservations. It is my understanding that the German socialist movement was much more moderate than it’s Russian counterpart, especially the factions that eventually gained supreme power in Soviet Russia. I’m afraid I could go on and on about how differently we view the possibilities of the political landscape in supposing a German victory but it really doesn’t have much to do with the op and my fingers would cramp ;\>. Very interesting talking with you Sparc.

Depends on what you mean with victorious. I happen to think that a complete victory by the Central Powers is more or less beyond the scope of speculation. I think the best victory they could ever have gotten was a return to the boarders of 1914.

As for the SPD in 1916 the relevant point is not that year, but the status in 1918. Victory or no victory they had by then achieved a pretty strong power base and it is unreasonable to surmise that this would evaporate at a peace with better conditions, or even a downright victory. To boot they had gained strong support from the Center and Christian Coalition, and not only because of their war politics.

As for the differences between the Bolsheviks and the German Social Democrats I do believe that the similarities were broader than you seem to believe, but as you said this is somewhat of a different debate.
