Putin is demanding for Crimea more or less what Hitler wanted for the Sudetenland: Russians ought to be in Russia. No doubt the Crimean Russians agree and, come Sunday, will vote accordingly. That would place a patina of democracy — or at least self-determination — over what is essentially a power grab, but it will be hard to argue that the Crimean Russians aren’t getting the government they want, if not the one they deserve.

So we can see — can’t we? — that Chamberlain was not such a noodle after all. He certainly appeased Hitler. But the Western world — needing Russian gas for Germany, Russian rubles for London flats — over time probably will do the same with Putin. Just as we — especially our European brethren — can see the logic of Putin’s demands, so could Chamberlain appreciate that the Sudeten Germans might be on the wrong side of the border. Hitler’s homicidal anti-Semitism, among other character blemishes, bothered them not a bit. No one’s perfect, after all.

The fly in my Sudeten ointment is that, as with Chamberlain in 1938, we are not sure with whom we are dealing. Hitler soon announced himself, making Chamberlain appear the fool then and forevermore. But what of Putin? Will he stop at Crimea or, after a pause, plunge into the rest of eastern Ukraine, which has many Russian speakers? And then, what next? Will he endeavor to protect ethnic Russians in, say, Estonia? Almost 25 percent of that country is ethnic Russian. How about Latvia, which is about 27 percent Russian. These are healthy numbers; if these Russian minorities become endangered — or are merely said to be — a Russian ruler has an obligation to act, da?
