America has become a war-centered nation and culture. From William J. Astore at antiwar.com:
War is America’s Growth Stock
When the Soviet Union fell in 1991, America heard something about “peace dividends” and “a new world order.” With the Soviet Union gone, the Cold War over, America could take all the hundreds of billions it had been spending on weapons and wars and spend it instead on America. We could, in theory, embrace peace, reinvest in America, and save our children from a world of incessant wars and preparations for the same.
It was not to be.
The collapse of the Soviet Union coincided with Desert Shield/Storm, when America allegedly kicked its “Vietnam Syndrome” once and for all, according to then-President George H.W. Bush. This “syndrome” was allegedly inhibiting America’s pursuit of righteous victory through military means, and the expulsion of Iraqi forces from Kuwait was allegedly proof that America was back and that military force had powerful efficacy for good.
Out went the idea of peace dividends. This was America’s moment to dominate, a Pax Americana achieved through military force or threats of the same. U.S. dominance of the Middle East contributed to the decision by Al Qaeda to launch attacks against the USA, but any U.S. culpability for 9/11 was swept away by another President Bush, George W., who explained that Al Qaeda had no rationale for 9/11 other than their hatred of American freedoms.
