You assume it's ignorance? I still don't know why you relate communism to somenthing that. Capitalism it's base on the idea of my own good, what's good for me it's fisrt, then the others. That's a selfish idea! as a way of living I think Socialism, not communism, it's veyr good, though economicly capitalism it's a bit more productive.
Then why doesn't the States eliminate the other big tirants in the world? The DROC (Congo) have one, Turkeministan has one, North Korea.... They list oin quite huge, and they just don't seem to mind! That Saddam was a bad person it's true, I don't argue that, but there are sthousands of bad people out there and he just decided to go to war with him...why?
When you are a president, it's true you are not the only on who decides, but you can make big effors to avoid things... If I'm a pacifist I will try to solve the things for a peaceful way, even though many people on my party or goverment, are not in favour of my actions. And what they did with the UN was awful! They are an International Organization in charge of maintaining World Peace, and they just ignore it! and now they are asking for help, for what they did wrong! for what they destroyed!
The U.S.A it's not the only county in this world, and not everything goes arround him.
Then, Bush has made an amzing campaign to show people that Muslims are terrorist and they are evil and all that, when it's not true! He can't even distinguish an Arab country from a Muslim! He doesn't understand really how they are (neither do I completely!) and he just use I don't know which paramentres to say "This is good and wrong". We are not like them, so you can't expect them to do and to be like we are.
