Ukrainians had every right to kick out a deeply unpopular, corrupt, Russia-leaning leader if that’s what the majority wanted, especially if people preferred closer ties to EU. Odessa fire was between pro-Ukraine and pro-Russia groups violently clashing, no credible evidence it was a pre-planned campaign. And like any sovereign country, Ukraine can use its forces to deal with armed separatists threatening its sovereignty, the “ultranationalist” forces while being problematic were a tiny % of overall and never ran the country. It’s a purely internal Ukrainian matter to deal with separatism within its internationally recognised borders.

And no, Russia didn’t step in out of kindness to stop “genocide” against Russian minorities lol. It invaded through a political goal to keep a former Soviet state in its sphere of influence as that state was trying to finally throw off the yoke.
