He’s not going to Poland. He’s not going to Kiev, unless the neo-Nazis start killing Russians, then he will.
You need to be more concerned about Jews in Russia and in the Crimea. Putler is not too worried about his own skinheads and their crimes.
One should not underestimate the trauma of World War 2 on the psyche of Russians (not to diminish its effect on other East Europeans, too). For them, losing 20+ million people only 70 years ago (more than half civilians) and having all of their country destroyed up to Petersburg, Moscow to the Caucasus, and then seeing neo-Nazis with their “kill the Muscovites and Kikes” taking a major role in the overthrow an elected government and taking a large portion of the new regimes post (and all of the security posts) has lit a fire of resistance among almost all Russians. They won’t accept it, and it was stupid to have orchestrated this.
The solution, I believe, is Finlandization (neutrality) for Ukraine and federalism with autonomy for the regions and respect for minorities, religions and languages.
For the US or NATO to fight and try to keep the neo-Nazis in power in Ukraine will absolutely lead to World War 3.
