The problem with Afghanistan is that there is no clear path to victory. This has always been the problem with Afghanistan. In Iraq, there was at least a plausible exit strategy. Iraq was a country that has a reasonably well educated population, a middle class of sorts, and which had a large standing army. If you could build up a civil society, rebuild the defense forces, then theoretically you could go home and let them fend for themselves.
Nothing like this exists in Afghanistan. The U.S. could kill every Taliban tomorrow - and then what? Go home? Leaving exactly what behind? Afghanistan is dirt poor. It has no ability to look after itself. It is shot through with tribalism and warlords. Pakistan next door is a breeding ground for radicals.
This notion that Afghanistan wouldn’t be a problem if only Bush hadn’t ‘taken his eye off the ball’ is ridiculous. Unless you can point to a strategy he could have undertaken that would have resulted in some form of ‘victory’ today, this is just Bush hatred masquerading as ‘support’ for the ‘right’ war.
The fact is, the war in Afghanistan isn’t going to end - at least, not on any terms that will make the American people very happy. More likely, Afghanistan is giong to be a permanent military frontier - the U.S. will need to maintain forces there indefinitely, of a size that at least allows for its own defense (i.e. it can’t be overrun, and it can maintain bases tht are secure). These forces will engage in constant skirmishes with the Taliban and Al-Qaida, and hopefully prevent the country from completely collapsing and being taken over by radicals again.
Be prepared for constant low levels of casualties, with no end in sight.
Or, the administration might ‘double down’, send a whole lot more troops into Afghanistan, and start making major expeditions into Taliban-held territory to kill as many as possible. In the proccess, the U.S. will take even more casualties. Hell, it might even be the right thing to do - I’d take the advice of the generals on the ground. But it’s not going to be easy, it’s not going to be pretty, and I have no idea how it leads to any sort of ‘victory’.
The strange thing is that, aside from a few people in this forum, the left has stopped caring. Even though Afghanistan is now deadlier than Iraq ever was (more casualties per soldier in-country are being taken in Afghanistan right now than in Iraq at the peak of the violence there). It seems war is only bad if a Republican is running it. Or maybe all those protests were just political theater. Just like how Bill Clinton could actually sign the Defense of Marriage Act with very little noise from the gay community, but they marched on Bush for merely upholding Clinton’s law.
