Afghanistan leader Karzai has threatened to join the Taliban if everybody doesn't get off his back about corruption and voter fraud. Nobody believes him, of course, because even he knows the Taliban would kill him in a New York minute if they get near him.
Karzai is in the very uncomfortable situation of needing all these foreigners in his country in order to have a country at all. There's no question that he needs them to restore order, establish infrastructure, etc. He can't muster the resources on his own to do any of it.
But guess what? We also need him. That's what he's saying with his rants. We do need him. So stop dropping in with demands and thinly veiled insults about integrity. He's getting sick of it. That's all he's saying.
