I firmly believe we are fighting evil in a world battleground. Radical Islamists want to bring the U.S.A down. We cannot stand by and let them do this piece by piece as they were attempting to do during the Clinton years. We need to push on, help Iraq become a democracy and spread that democracy in the Middle East. It's either that or let democracy die worldwide.
I don't think they just want to bring the US down. I think they want to bring all of western civilization down, Christianity, Judaism and all freedom. They want us to become barbarians just like them.
