"One of the most intriguing mysteries of World War II is why Germany and the Allies did not use chemical and biological weapons against each other. As the Third Reich crumbled, it seemed ever more likely that Hitler would employ weapons of mass destruction.
The reason he didn’t was deterrence. Both sides feared that, as in World War I, once one side used chemical weapons, so would their opponents. It turned out that German nerve gases like sarin were far more effective than Allied chemical weapons, such as mustard gas, but the Germans didn’t know that." - Michael Peck, "What If Hitler Used Chemical Weapons Against the Allies on D-Day?" The National Interest, June 14, 2020.
A question that has perplexed Western historiography on WWII, which is dominated by Jewish voices, is why Hitler didn't use chemical weapons against the Allied invasion of Normandy considering his regime had no qualms about using gas on Jewish civilians.
Was he simply afraid that his enemy would return the favour in spades?
Or did he have more noble intentions?
This question is fatal to the Holocaust narrative and exposes it as a total lie.
A likely explanation is that Hitler prohibited the use of chemical weapons on moral grounds against both military and civilian targets.
Hitler personally experienced gas warfare in the trenches of WWI and that painful memory undoubtedly influenced his decision to not repeat the errors of his military superiors.
The black and white mind is incapable of giving the benefit of the doubt to Hitler because in that myopic worldview he's the epitome of the Devil. Facts do not sway. Once you are convinced of something on an emotional level it's hard to dislodge that belief.
The fact is the Nazi war machine was more moral than its adversaries, especially the Soviets.
There's no question repugnant characters made their way up the ranks of the Nazi regime. Government power always attracts the worst cretins and murderers in all societies. But, as a matter of state policy, which fell under the final authority of Hitler, chemical weapons and other weapons of mass destruction were prohibited from military and civilian use for moral reasons.
