He's still around?

Ex-prez Clinton Wows Young AIDS Crowd. Of course, being who he is, he can't help but slap at Bush, saying not enough is being spent on the global AIDS epidemic. The UN estimates it'll take $10 billion annually to fight the epidemic.

"Our fair share would be $2.5 billion," he [Clinton] said. "The difference of where we are and where we need to be is less than two months of war in Afghanistan."

Two questions: 1) How is 25% of the bill "our fair share"?

2) How much each year did Clinton spend/contribute?
