I don't think he's gonna have much choice. the american public seems to have had it with iraq, but most of us are still pretty pissed about bin laden and the wtc.
and since i was already angry about the taliban prior to 9/11, i see more than one axe to grind there. what those guys do to people over their frakkin' islamic bullshit is barbaric.
You have much more faith in the american public than I do. I estimate the appetite of the American people and Democrats to be at most two years and 1500 american deaths. Don't have a lot on which to base this assessment except the current war. It was about Mar 2005 (two years after the invasion) that approval of the war dropped below 50%. Correspondingly, in Mar 2005, the american fatality count was about 1500.
Using that stat, I predict that, despite their current hawkish rhetoric on Afghanistan, Obama and his fellow Democrats will abandon Afghanistan within two years of taking office...or when the Afghan fataility count exceeds 1500.
Therefore, if Obama wins, he'll have to finish this war on terror in two years before the liberal peaceniks force his hand. But IMHO, there is now way that we can clean up and stablize Afghanistan in two years or less. It will require considerably more time...and unfortunately neither Obama and his fellow Dems have the requisite backbone or endurance.
