You might as well ask the same question about Afghanistan: none of the people on the planes on 9/11 were Afghans. Did/do you oppose our actions in Afghanistan on that basis? Let us know....
Well let's see, we went into Iraq with the express purpose of taking down its leader and foist our own political vision upon them. A leader that, ha ha, WE put into power! Now its a huge surprise that democracy won't readily root into soil which is so foreign to it.
In Afghanistan, we are pursuing a terrorist leader and his gang, NOT displacing the government, unless you can enlighten me further on this score.
