Maybe I am wrong, but it just strikes me as so cynical that NOW, because Ukraine has shown it isn't a pushover, that everyone is deciding to send arms to Ukraine to help it counter Russia and/or engage in stricter sanctions. This, IMO, should have been the position of the West from the get-go, that if Putin invades Ukraine, the West will help the Ukrainians make him bleed. Such action also sends a strong message to China regarding Taiwan IMO. But instead everyone just sort of shrugged it seemed and said, "Well it sucks, but bye-bye Ukrainians," then when Ukraine doesn't roll over, you see about-faces starting to happen, with Germany now deciding to send arms after initially refusing to and Australia deciding to send arms after first just promising "non-lethal" aid and the U.S. as well sending arms.
When Putin first invaded, I had no idea how Ukraine's forces would fare and was inclined to think they'd just be a pancake in front of a Russian steamroller, but at the same time, it reminded me of the German invasion of the Soviet Union in 1941, when everyone wrote off the Soviet Union. Even if a freedom-desiring nation seems like it's in a hopeless situation, IMO the West should always try to help, because well you never know.
