Why does the U.S. government want to rule the world when the U.S. is blessed with the world’s most potent defensive protections? From William J. Astore at antiwar.com:
And the Insanity of Wanting to Rule the World
What will historians say decades or centuries from now when the U.S. empire collapses into ruin? How will they explain it?
Consider the United States in the big picture. I see a country with unique strengths. Two wide oceans protecting us. A long secure border with Canada. A securable border with Mexico, the current immigrant “crisis” be damned. Canada and Mexico aren’t our enemies. No invasion is coming from them. As a country, the USA occupies a geographical/global position that is uniquely safe and advantageous.
Why are we so fearful? Why do we spend a trillion dollars (or more) each year on national “defense”?

Of course, I put “defense” in quotes because the USA is an empire with a military configured for offense. Global reach, global power, was the motto of my service, the U.S. Air Force. The U.S. military strives for full-spectrum dominance, meaning total control of the land, sea, air, space, and cyberspace, justified in the false name of “defense.” The cost of this febrile quest for dominance is, I believe, ultimately unbearable. Why do we persist in such folly?
What country would dare to attack the USA? Other than small terrorist networks like Al Qaeda, no country, no people, no leaders in their right mind would dare attack us, let alone invade us. They know they’d likely be obliterated if they did. Does anyone truly fear an attack on the USA from China? Russia? Iran? North Korea? Given America’s belligerence, evidence of our unbridled vengeance after Pearl Harbor and 9/11, and our vast arsenal of highly destructive weaponry, including thousands of nuclear warheads, anyone attacking the U.S. would be pursuing a death wish.
