There appear to be three distinct groups opposing U.S. aid to Ukraine:
(1) The Putin/Trump Caucus in Congress — A submissive Donald Trump bows to Vladimir Putin, and spineless Rethuglicans in Congress bow to Trump. These stooges howl "America First!" while putting Putin's Russia first and America and its democratic allies last.
(2) The Neville Chamberlain Caucus — British PM Neville Chamberlain believed that ceding the Sudetenland of Czechoslovakia to Nazi Germany in 1938 would guarantee "peace for our time." Hitler had convincingly asserted that the region bordered Germany and the population was predominantly German speaking and had ethnic ties to Germany. He quickly violated the Munich Agreement, invading and conquering most of Europe. Putin makes exactly the same arguments of ethnic homogeneity to justify his war crimes in Ukraine. The Baltic states and Finland (present NATO members), like Ukraine, are also on Russia's border. NATO's charter would demand an immediate and staggering military response to any similar Russian aggression. Those who claim to be advocates for peace should think about that at their next pro-Putin rally.
