Who is justifying it? To be clear, I'm a pacifist and against all wars. I too believe in the self sovereignty of people. One can be against the Russian invasion, and for the peace treaty that was about to be signed spring 2022 before Boris Johnson came and put a stop to it. Diplomacy over bombs I say, but our leaders see it as economical to fund a war against Russia, so that Ukrainians can fight it instead of our guys. I think that's inhumane and unwise.
