You make absolutely no sense.
The Syrian war was started by American supported rebels and ISIS. The SDF (al Nusra, aka al Qaeda in Syria) has been supported by the Americans throughout the entire war, until Trump took office, when he promptly ended the CIA program which armed them. Are you saying the American government has been trying to achieve Russian geopolitical objectives since they invaded Iraq?
The problem with the Ukraine is the fact that it is currently controlled by Nazis. And I mean real Nazis, descendants of Hitlers group of Nazis. Look at the helmets of the Azov brigade. Spoiler alert: Russians hate Nazis more than you do. They had a really nasty war a long time ago. But hey, Joe Biden's son is on the board of the Ukraine energy company now, so apparently the Democrats have no problem with real Nazis.
What's wrong with Brexit and Catalan independence? Self determination and self rule are human rights. To take that away from people is tyranny or slavery. If Russia is supporting self determination and self rule, they are supporting freedom.
Politicians are trash, no one needs to do anything to impugn them, the politicians are quite capable of that on their own.
