The Chechen issue isn’t really analagous to the “Jewish Question.” The Chechens have long been an active thorn in Russia’s side. According to the Soviets, they collaborated with the Nazis in World War 2, and earned their deportation to Central Asia. A number of Caucasian (particularly Moslem) peoples collaborated. The Chechens are conducting active terror campaigns in Russia, and, I might add, in the United States as well. In the Russian/Chechen feud it’s hard to tell who is right and who is wrong. But in no way do I see equivalency in that situation with the “Jewish Question” in 1938.
Objectively, you're correct, but subjectively?
In 1938 your average American was at least somewhat anti-Semitic -- let's use HL Menken as our archetype here.
Americans knew that Jews were often mistreated (i.e., pogroms in Russia), and had seen enough propaganda to suppose there must be good reasons for it.
So they did not take Hitler's actions against Jews by early 1938 as particularly unusual or alarming.
Compare today: your average American tries hard not to be "anti-Muslim", just "anti-radical-Muslim".
We know that Muslims in places like Chechnya are often mistreated (i.e., Putin's war against them), and have seen enough news reports to suppose there must be good reasons for it.
So we do not take Putin's actions against Chechen Muslims as particularly unusual or alarming.
No, of course I'm not saying objectively Putin is Hitler in this regard.
But Putin is certainly subjectively perceived here in roughly the same way Hitler was in early 1938.
