Buchanan if you seriously think that Putin's Russia is not Stalin's Russia you are delusional. They're Communists, get it?? And yeah we do have "war guarantees", with both Japan and South Korea. And probably Taiwan and the Philippines as well. Are we going to let our allies fall to Communists again like we did in Vietnam?? I'm sick and tired of so called American "Statesman" calling for reneging on our friends and allies. If the U.S. pulls out of Korea you can bet your bottom dollar that N. Korea will be on the doorstep of Seoul the next morning.
