The main sentiment here, especially amongst the older people is, "russia is strong enough, that they can do the stuff america has been doing for decades now", but due to media influences, it's not a "war for democracy" and "saving the locals", as the americans would paint eg. attacking afghanistan after a few saudis flew a few planes into a few buildings.
My personal and very contraversial opinion is, that every country that currently has soldiers as a part of an occupying force in any country, should just shut the fuck up, and clean up their own messes first.
Hundreds of thousands of us were out in the streets protesting when western countries attacked Iraq. Most of us are the same people angry about Russia in Ukraine.
In the US, with only two parties to choose from, so-called "centrists" and "liberals" in the US almost all fell in line and nobody could do anything to punish them. "Who else are you going to vote for?"
Similar dynamic in the UK. Labour ("New Labour") was in power and supported the invasion for god knows what reason. Hugely unpopular move, but what were voters on the left going to do about it?
