[emoji38] it seems as you don't understand anything about the US. The US built a system around economy and the system works. The entire world doesn't have that system, the Chinese economy, the Russian or the European economies depend on our business, etc. Its not our fault that people like you, running other stupid regimes were too busy making their families wealthier and not their nation. We made a nation wealthy and a system based on that.
Are you surprised that we control the world? I won't be. Had others been focused on their people and their country's growth in the economic world, there would be multiple super powers for the past 50 years or so. How is others loss our gain? Its not. Our gain is ours, because of how we designed our system back in WWII after the great depression and by putting great thoughts towards the future. The others.....simply didn't think that far.
Why should I be responsible for another person's lack of sense or even stupidity? The regimes you mentioned are run by idiots and tyrants. Period.
On the economic and Petro Dollar front. I think you and many, many others are VERY misguided thinking that the US does everything for Petro dollars. When Iraq war was finished and people like you were thinking "America stole oil", we were paying the highest prices in our history at the gas stations, over $ 4 per gallon (compared to $ 2+ before the war). So that clearly tells you what we took. ZERO!
Also, read up on America's oil and gas capacity. We are actually the largest (or number two) oil producing and exporting country on the planet with one of the largest oil reserves. Because of this same b.s that you wrote on here, we even stopped buying oil from KSA as we didn't need it and we don't want to be involved with their mess. I suggest you learn more about America than what they teach you on your country's tv and newspaper and experience America to learn it. There is a reason the entire globe (Indians, Russians, Middle Easterners, Pakistanis, etc, etc,) come to the US for education. Clearly there is a LOT more to America than the so called "Petro Dollars"!!
