Where Has Imperialistic Power Gone?
"As the new century dawned, a crew led by George W. Bush and Dick Cheney ascended to power in Washington. They were the first administration ever largely born of a think tank (with the ambitious name Project for a New American Century). Long before 9/11 gave them their opportunity to set the American military loose on the planet, they were already dreaming of an all-American imperium that would outshine the British or Roman empires.
Of course, who doesn’t know what happened next? Though they imagined organizing a Pax Americana in the Middle East and then on a planetary scale, theirs didn’t turn out to be an organizational vision at all. They got bogged down in Afghanistan, destabilizing neighboring Pakistan. They got bogged down in Iraq, having punched a hole through the heart of the planet's oil heartlands and set off a Sunni-Shiite regional civil war, whose casualty lists continue to stagger the imagination. In the process, they never came close to their dream of bringing Tehran to its knees, no less establishing even the most rudimentary version of that Pax Americana."
