What happened to the War on Terrorism?

Whatever happened to fighting a War on Terrorism? I mean why have we diverted our attention from the enemy Al-Qaeda and turned it to Iraq? Why did we stop chasing Osama Bin Laden, the man who actually attacked us, to go off on an elective war against a country that hasn't done anything in ten years? Well, because of the diversion in Iraq we have severely weakened our ability to root out terrorism. We are now essentially stuck in this country for at least a decade with a hundred thousand troops when those troops are needed elsewhere. The Iraq war has caused us to become increasingly weak in East Asia, where a true threat - North Korea - exists. This foreign policy makes no sense at all to me. -- John Murphy
