Why do Christians support Iraq War?

I fail to make the connection between the Bible and how it justifies such actions.

It's not "Christians" who support the war in Iraq. It's people from all walks of life who for some reason or other feel that the war is just or good or whatever. Personally I just want to let bygones be bygones, develope the electric car so that we can pull out of the Middle East and let the radicals get back to killing each other in stead of us, and then kick back and read my books whilst enjoying three healthy meals a day.
