Appeasement does not work. It has never worked. It didnt work in Sudetenland

And it didn't work for Russia when they appeased the USA as they marched NATO all across Eastern Europe and installed nuclear capabilities aimed at Russia. Russia has appeased the USA for too long. They decided to act in Ukraine finally because Ukraine is THE strategic red line. Both Napoleon and The Third Reich invaded Russia through Ukraine because it is strategically the best path. The USA took up nearly every other borderland with Russia except Ukraine, saving it for last, and Russia appeased and appeased. It stopped at Ukraine.
