Without condoning it, that wasn't an all out war. It's a really complicated situation and seems more like a political action. Less people were killed than in the Capitol breach, don't think anyone is referring to that as the second civil war.
While I agree with you that it's purely political, it's a war nonetheless. The Capitol breach resulted in 5 deaths, while it took more than 13000 lives in Ukraine.
If it's not a war, then we can safely assume that even a villager in Ukraine has accessed to military grade equipment that even some countries can't get access to.
It would be not bloodless if Ukrainian soldiers would not try by all possible means to avoid the shooting, trying to treat russians as former brothers and stop russia’s hostile actions by negiotiations.
