Ooh, picking fights on the internet...guess that makes you a tough guy.
1. The username "Big Brother" has no deep meaning to it like you seem to think. It just means I'm a fan of classic literature.
2. Do I think I'm great? No. We all have different perception of what constitutes greatness. A person who is great is someone who had a major impact on human society, be it positive or negative. I'm just an average everyday guy.
3. We didn't invade Iraq because of oil, otherwise the prices won't be so high. Bush invaded on bad information from the CIA. We don't have and never did have any reason to go into Iraq. As for your other question, if things can be solved by negotiations and diplomacy then I'd prefer that over bloodshed.
4. We don't "Divide smaller countries" or "make them fight". We do however have a problem of playing mediator in world conflicts and that in turn leads us to policing the nations in question.
5. My doom is nigh: If it is my fate, then so be it!
6. Russians are the new leaders: FYI, they're not. If any country will be the "new leaders" it'll be the People's Republic of China. Everyone depends on China for trade amongst other things.
7. Watch away. America welcomes you with open arms.
