The governments in Washington committed many crimes, but on occasion Washington prevented crimes. Remember President Eisenhower's ultimatum to Washington's British, French, and Israeli allies to remove themselves from the Suez Canal in Egypt or else.
Today Washington pushes its allies to commit crimes against humanity. That is what NATO and the National Endowment for Democracy are for.
In my lifetime Americans have always had a good opinion of themselves. But in the 21st century, this good opinion has hyper-jumped into hubris and arrogance. If you haven't been around very long in terms of a human life, you don't see this. But older people do.
Just as the Roman Empire ended in the destruction of the Roman people, the American Empire will end in the destruction of the American people. Judging from histories, Roman citizens were superior to American citizens; yet, Rome failed.
Americans shouldn't expect any other outcome. The price to be paid for insouciance, self-satisfaction, and complicity is high.
