“Putin refuses to recognize Ukraine as a nation. Maybe the EU needs to step up and do more to help Ukraine. But Putin is the invader.”
You seriously need to read a history book and stop watching CNN.
Yes indeed. Studying real history and not U-Toob videos will show you why Ukraine should get all the support we can give her. Let me hand you a reading assignment: Post War by Tony Judt, Bloodlands by Timothy Snyder, Churchill, by Lord Moran, both books by M. Stanton Evans and Herbert Romerstein. There are hundreds of others, but those will occupy the typical "useful idiot"(Lenin's term, not mine) for a few weeks, if not months.
