Russia is strong, but the longer they wait, Ukraine gets better prepared. Of course, Russia could crush Ukraine, but they don't have the element of a shady surprise like they did with Crimea in 2014, and while they could potentially attack from two or three fronts (east, black sea, Belarus), it's not exactly quite that straightforward - even for Putin - to attack "brethren people" and deal with the public response, especially from mothers, when their sons come home in bags. That caused some turmoil during the first years of the war in Crimea/Eastern Ukraine, even if nothing major.
I'm not saying Russia won't invade; quite the contrary, they most definitely could do that and there's no denying it sounds extremely threatening and speaking for myself, as someone living in the most southeast area of Finland, it's not going to make me feel too much at ease, but invading Ukraine wouldn't exactly be a walk in the park either
Putin is clever... He keeps pushing the line and the "west" lets him do that. And every time, Putin pushes it a bit further. And now, if he stands down and the immediate threat of a full-scale invasion ceases it'd make the overall situation seem so much better that a lot of people would gladly sigh for relief and kind of choose to ignore that... yes, Russia has actually already invaded Ukraine and been involved in war there since 2014.
Oh well. It's not like I have any answers either. The world is broken and all, but it's quite sad how Europe that has enjoyed quite a prosperous era for so long, is broken as well.
