Russia’s leader Vladimir Putin seems Jew-friendly to me (particularly to Chabad), but it is interesting that most of his enemies in Russia are Jewish. I doubt that most Jews in Russia oppose him.
I am not exactly sure why so many people in the American media want to stir up a WWIII with Putin.
If I were Putin, I would be furious at Western involvement in the lands next to me such as Ukraine and Poland. I would want to enforce the equivalent of the Monroe Doctrine in my part of the world.
In my personal experience of Jewish life, I’ve never noticed significant anti-Putin sentiment but I have noticed a knee-jerk response in many Jews bearing a historical grudge that Russia sucks.
