If you want the least amount of blood spilled, you should be advocating to send weapons to Ukraine.
There were peace offers from Russia a year ago that would have had them give up a portion of their occupied territory for peace. Ukraine declined because they believed they had the means to take back even more territory (at the expense of a lot more Ukrainian blood).
We’d have avoided the last year’s bloodshed if we stopped sending weapons back then.
What we are seeing right now is the absolute worst possible scenario for Ukrainians; a quick win or loss wouldn’t have killed 100K+, destroyed millions of homes, and displaced millions of refugees.
signaling to Russia that they can’t invade other countries for free
Russia can barely manage to invade the Russian-speaking parts of Ukraine, do you really think they’re planning to invade NATO next?
