It seems everybody hates the U.S already. It seems that people despise us and it's quite possibly due to jealousy. I still believe we have one of the strongest army's in the entire world, the only possible threat would be China. The minute any country gets themselves into a jam they call on the U.S for help, for money or weapons or assistance. They hate us until they need us and that's just not right.
If the U.S has to start a war, to defend itself against whatever nation harvered these terrorist, so be it. They wanted a war, and they should get one, just they'll be against a nation with one of the most powerful military forces in the world. I say if they can kill 1000+ people without thinking about it and even celebrate it...
This country fought long and hard for his independance, and then its freedom. It may not be perfect, it may be flawed and it may be a baby nation in comparison to all the others, but it's my home and despite it all I'm happy here. If I was called to defend my nation, to defend my beliefs and freedom, then so be it. No nation, U.S or Islamic, Palestenian, etc. deserves what happened today. Anybody who can cause such a tragedy is in serious need of a bullet.
If Americans did this to buildings in another country causing thousands of lives, then they deserve the bullet just as much. But I'm willing to bet 95% of the people in the WTC was pretty innocent and had nothing to do with whatever cause the opposing terrorist organization had to blow this building up.
