“Afghanistan is ready right now,” Karzai said in a statement, “to take all security responsibilities completely.”
With so much evidence to the contrary, it is tempting to assume that Karzai’s pronouncement is simply another provocation from a war-weary leader angered by American military lapses, the most recent of which was a U.S. Army staff sergeant’s alleged shooting rampage that killed 16 Afghan civilians last weekend. Karzai said Friday that he is “at the end of the rope” over how the U.S. military has handled the incident.
I have no idea whether Karzai and his people can maintain security in the country, but I'm not sure what "evidence to the contrary" there is. There's a reasonable amount of evidence that a large US troop presence hasn't exactly made the place a security paradise. The country we've occupied is totally fucked up so that's evidence we need to continue the occupation seems to be the logic.
Things may go to hell when we're gone, but it isn't exactly paradise with us there.
