Since this is an exercise in pure speculation:
Argentina takes Las Malvinas* back.
Dominican Republic takes Puerto Rico**.
Cuba kicks the US out of Guantanamo.
Grenada declares war against the US***.
Mexico sends covert operatives into Texas, New Mexico, California and Arizona.
Its better for nukes to remain on the table, while I doubt that the US would require nukes , you can make an argument for the Euros to be thinking a few nuclear strikes while they still have the capability would be an advantage.
There is no way we would let them remain neutral, in this case its to our advantage to blackmail them with nukes to keep the gas fields and oil reserves out of continental europe. Add to that the Russians have SLBMs and SLCM subs, plus their few aircraft carriers.
Leaving them neutral now allows them to swing either way, which would decide the conflict, I am pretty sure that the Euros would be thinking the same way.
Russia comes in on the side of the EU and they can use their own system, otherwise most of all weapons systems have secondary nav capabilities. The EU navy assets from France , Britain and Germany can tie into the AEGIS system, but can probably be recoded to deny any entry into the system.
Not really that hard to co-ordinate, as for the most part your looking at either militaries that have worked with each other previously , or relegated to air defense.
I honestly think that you are giving the Italians a bad rap, when it came to Desert Storm, the Italian airforce took heavy casualties when it went downtown in Bagdad, where as the German airforce was loathe to even get close to any sort of conflict, not to mention that Italian guy that had his head separated in Iraq, going out with style, stating this is how an Italian dies, makes me want to not pigeon hole them into the old style Italian Admiral and glass bottom boat jokes.
Alot of those bases were designed around the idea that the Russians might have overwhelmed them , given that the Euro war would not be a bolt out of the blue , its likely that Brussels would have demanded that the US forces be removed , given enough time any remaining equipment could probably be de milled.
There is another thread regarding the destruction of vehicle engines in the cash for clunkers program, to do this , you add a cocktail of water , silica, and something else , let the engine run and it seizes. The US campaign in the EU theatre would probably resemble this.
Its really about which EU member nation caves first, I dont think that a collective of nations could maintain a cohesive force for long.

I can just imagine the green partys reaction to this
Um, the American Govt just has to close the borders and we grind to a halt.
Declan
You really believe that the USA or Russia would let China come out as top dog ?? or India for that matter.
Its really why nukes cannot remain off the table, in the OP.
Declan
I think they probably could actually; nothing firms up alliances like being attacked by an enemy who can squash any of you separately.
DT I think you’re probably right
Agreed. So if the US feels like they can attack, and beat, 27 countries simultaneously, hey, you go for it!
Irresistible force (the U.S.) meets immovable object (the E.U.).
I can see the U.S. attempting to gain some sort of initiative in the offensive sense, but if the UK is hostile there’s really no practical way to do it…
Unless… you take the Azores as a staging ground to invade Portugal, the U.S. Navy would win this scrap, thus leaving naval superiority (and air, if they can fix up a base on the Azores) for an invasion of Europe proper.
Here comes the but - even if the U.S. somehow pulled this off, they’ve nowhere to go. They could take down Portugal, Spain would be a tougher nut to crack (especially with European reinforcements pouring in from the Med and over the Pyranees, whilst the U.S. is forced to rely on reinforcements sent across the Atlantic). Even if the battle for Spain is won, then what? Move on to France, Germany, the U.K., Poland? Not a hope in hell - there isn’t the manpower to secure the entire E.U. (or even a part of it). Redirect U.S. forces out of Iberia, and Spain and Portugal are back in the game. These are nations that have existed for a long time, capitulation wouldn’t be an option in the face of foreign invasion.
I can’t see any logical options but for;
Hold it- we have to conquer/occupy the entire continent of Europe AND simultaneously lock down a 3,000 mile border?
I think you might be giving us just a BIT too much credit! We’d need several million more trained, armed men to do either of those things, let alone both!
See the thing is this:
The USA is just over 200 years old, Europe is 1000s of years ahead of you guys in warfare.
We’re past masters at wholesale killing, burning of cities, massacre of civilians not to mention torture of whomever gets on our tits.
Collateral damage?.. fuck that, we don’t give a shit who gets killed or which town or city or village or hamlet gets offed. The USA is too concerned about collateral and this is where we have you beat.
I suggest you just surrender now before we send in the Spanish Inquisition, you weren’t expecting that, were you?
Yes, but you’ve really gone soft in the last couple of decades. I mean, it used to be all about the pillaging and bludgeoning, but now the best you can do is a street protest against genetically modified foods.
And not forgetting alcohol as a force for strength. You just can’t win battles with teetotal bible thumpers. Why the UK alone, with our proud history of dipsomania, will whip the US with our unencumbered violence, bravery and patriotic sentimentality (I wuv you EeeYooo).
Oh. I don’t know. We had a respectable slaughter down in the Balkans. Plenty of pillaging and bludgeoning. Murder, rape and genocide. And other wholesome fun. I’m sure they’re itching for another go. Another little brawl over in the Caucasus. Putin could have done so much more if we had let him. A proper leader don’t talk about rubbish like hopeandchange, he threaten to hang his neighbours by the balls.
And if required we can allus call on ex-footie hooligans to really give those Merkins a good sound thrashing.
Innit?
The feared 42nd Royal Hooligans regiment?
Simple: we bomb the cider factory. Good luck getting any mayhem out of that lot without Frosty Jack’s.
Cider?
Those guys aint called Lager Louts for nothing
We all know a war between the US and Europe would be horrible, but it does present an opportunity to once and for all which sport deserves to be called football.
Yes there are. When Mars Attacks.
I’m afraid the US would be fighting more than just Europe on that one. It would be fighting the entire world. 350 million people vs. 7 billion…
You guys really are in a teeny tiny insy winsy minority on this one. 
China and India, the two biggest countries in the world, couldn’t give a rat’s ass about EITHER type of football.
