Afghanistan and Iraq

I am finding myself asking why we are still in Afghanistan and Iraq. Did we not invade Afghanistan to go after the terrorist responsible for 9/11? Now what are we doing? Nation Building yet again? I don't know about you all, but with the economy in the state it is in, how can we afford to rebuild two nations and continue to fund our military and keep our own heads above water here at home? Does Obama know the answer? Will we just keep printing more money to support our efforts foreign and domestic. I thought Obama was the anti-war candidate. He sounds like a another Bush with a new found way of not only screwing us abroad but by sticking it in our ass even harder at home with his ridiculous domestic issues. He makes George Bush look like a fiscal conservative. When will it end? Comments anyone?
