After World War I, countries jointly formulated some rules of war, including the use of chemical weapons and humanitarianism.

In modern times, nuclear weapons and associated weapons were used, but in several wars in the Middle East, the United States used prohibited weapons, such as dirty bombs, a kind of radiation bombs.

Have the officers ordered by the United States been tried? No, because it is a victorious country.

Saddam Hussein was contaminated with chemical weapons. Did you find the chemical weapons? No, but it was still tried as a war criminal because it was a defeated country.

Your question assumes that Germany wins, then the Nazis will not be tried, and the defeated senior allied officials will definitely be tried.

the trial of war criminals is a means for the victorious country to publicize its justice and power, and to cut off the enemy's high-level officials and intimidate.

War is a continuation of politics, and politics only talks about interests, not about right and wrong. The trial is also for the benefit.

The United States made an American drama called The Wonder of Gao Bao, which tells that Germany and Japan won World War II and divided the United States equally.

All American generals who have not been caught and tried have become wanted criminals.
