When foreign diplomats are all summoned home, and their governments close the embassies down the street, you may expect the bombs to fall.  People of Iran, I hope you can turn your government around, but the US leadership under President Obama gave you no encouragement, and your own leadership seems utterly determined to summon mass destruction.

Canada just closed its embassy in Tehran.

My friends in Tehran, now would be a good time, I think, to visit family in the more remote parts of the country.
