Hey, horns, you say:

"What exactly is so terrible about the fact that President Karzai was assured that US aid and support would not disapear and he would not have to worry about being abandoned."

So how much aid did the Bush administration budget for him this year? I read that it was ZERO dollars. Fortunately Congress was (for once) ashamed to be so two-faced, and budgeted some money for aid and support to Afghanistan.

So what's so terrible about lying to your allies, leaving them in the lurch, and then getting upset when other countries don't trust you to follow through and do the job right instead of just making things worse?
