I know that trying to read and understand the public comments of a religious fanatic is a mug's game. But Mahmoud Ahmadinejad's recent return and return to the Jewish question, the new appeal to Europe to take Israel's Jews, his commitment to "wipe Israel off the map," and his pursuit of nuclear weaponry ... don't they all suggest something to you? When you put it all together with his eschatological theology, it's not very, shall we say, reassuring.  We always kick ourselves for not taking warnings seriously. But some warnings are not in code, or intercepted by NSA wiretaps. Some are made in the light of day on a very large megaphone.
