Diplomacy does not equal appeasement, and it’s been known to prevent wars and bloodshed. From Ryan McMaken at mises.org:
With proponents of military intervention and war, it’s always 1938, and every attempt to substitute diplomacy for escalation and war is “appeasement.”
Last week, for example, Ukrainian legislator Lesia Vasylenko accused Western leaders of appeasement during Moscow’s invasion of Ukraine, stating, “This is the same as 1938 when also the world and the United States in particular were averting their eyes from what was being done by Hitler and his Nazi Party.” The week before that, Estonian legislator Marko Mihkelson declared, “I hope I’m wrong but I smell ‘Munich’ here. ”
These, of course, are references to the notorious Munich conference of 1938, when UK prime minister Neville Chamberlain (and others) agreed to allow Adolf Hitler’s Germany to annex the Sudetenland in Czechoslovakia as a means to avoid a general war in Europe. The “appeasement,” of course, failed to prevent war because Hitler’s regime actually planned to annex much more than that.
