fred always seems to get it right and here he's even more accurate though you true believers won't like what he has to say;

Many people I talk to seem to think American foreign policy has something to do with democracy, human rights, national security, or maybe terrorism or freedom, or niceness, or something. It is a curious belief, Washington being interested in all of them. Other people are simply puzzled, seeing no pattern in America’s international behavior. Really, the explanation is simple.

The reason of course is empire, the desire for which is an ancient and innate part of mankind’s cerebral package. Parthian, Roman, Aztec, Hapsburg, British. It never stops.

When the Soviet Empire collapsed, America appeared poised to establish the first truly world empire. The developed countries were American vassals in effect if not in name, many of them occupied by American troops: Among others, Europe, Canada, Japan, South Korea, Latin America, Saudi Arabia, and Australia. The US had by far the dominant economy and the biggest military, controlled the IMF, NATO, the dollar, SWIFT, and enjoyed technological superiority.. Russia was in chaos, China a distant smudge on the horizon.

Powerful groups in Washington, such as PNAC, began angling towed aggrandizement, but the real lunge came with the attack on Iraq. Current foreign policy openly focuses on dominating the planet. The astonishing thing is that some people don’t notice.

The world runs on oil. Controlling the supply conveys almost absolute power over those countries that do not have their own. (For example, the Japanese would soon be eating each other if their oil were cut off.) Saudi Arabia is an American protectorate,and, having seen what happened to Iraq, knows that it can be conquered in short order if it gets out of line. The U. S. Navy could easily block tanker traffic from Hormuz to any or all countries............http://www.unz.com/freed/the-empire-now-or-never/
