Yeah, except this political party exists for a reason, that being Ukraine has always had a Russian population and ties with Russia owing to its history. It's not like the political party is an invading entity.Just for a little context... the servant of the people's party has 250 seats in parliament and the next biggest party 'For Life' has 37 ( which is who I guess you're talking about? ). Anyway its an openly Pro-Russian party, and Russia invaded their country. You think they let confederates into the government during the civil war? You think Stalin let Nazis walk around his cabinet after Hitler invaded? No. Its a necessary measure in times of war. The existence of the state is at risk, there could be no bigger stake.
And if we're going to talk about context then let's not pretend that the USA and UK weren't dicking around in Ukraine and instigated the 'revolution' back in 2014, because they most certainly did. That is the actual origin story of where we are now, versus the 'pUtIn iS a NaZi' idea which is about as deep as a frisbee.
How many times have we been here before, where the West has been deliberately arming and manipulating a nations politics only to turn around later and go "wE muSt gO to wAr!!". It's so obvious man, come on. Anyone who can't see that repeating pattern by now just has their head up their ass and is in denial over what the West is actually about, specifically what the USA is about - do I need to list the number of nations invaded and/or destabilized by CIA operations?
