If you are unable to differeniate between the Military Industrial Complex being out of control (Iraq, Afghanistan, Viet Nam), and a necessary military defense to prevent another megomaniac from empire building and genocide in Europe, you should stop opining on such things until you educate yourself.
I realize there are nuances to these things which may go right over your head. However, the appeasement of Putin, in allowing him to keep the Crimea, has emboldened him to go after the rest of the Ukraine, exactly mirrors Chamberlain's appeasement of Hitler in letting him keep Austria, leading him to invade Poland, and WWII.
Putin is already talking about taking the NAZI's in Poland, just like he's still claiming Zelensky is a NAZI. Go read a history book and get some perspective.
