Josh Marshall puts his finger right on it:

Hitler has become such a throwaway reference or comparison for whatever penny-ante dictator we’re up in arms about at the moment that the reference has been drained of much of its meaning and horror. But with the Munich agreement and how ‘time is not on our side’ and so forth, this is beyond nonsense.

It’s almost an insult to what the world faced in the late 1930s. Germany, industrial powerhouse, with arguably the most powerful army in the world, at the forefront of technology, overawing and invading neighboring countries. Iran, minor economic power, second or third-rate military power, which may get a couple of small nuclear-weapons compared to the couple hundred high-end nuclear warheads in Israel’s arsenal (plus, a robust second strike capacity, as Fareed notes) and the many thousands we have — and our blue water navy, satellites, air force. Please. Time’s running out for us? We’re going to look back on this fifty years from now and see the non-podhoretz-loons as the Chamberlains of the day? I don’t know what to say.

I do: They must be stopped.
