Iran is a country in deep trouble, having been condemned by the international community and by its many dissidents- condemned by everyone, it seems, except of course its close ally Iraq, and that other 'Axis of Evil' outpost, North Korea.
Now Ahmadinejad  has put together his Cabinet, and he has made one extremely clever choice. I refer, of course, to his Defense Minister, Ahmad Vahidi, a man wanted by Interpol for terrorist activities in Argentina in 1994, and the one man, I think, who could restore the reputation of Ahmadinejehad's tawdry regime, both with the international community, and with a fair (possibly overwhelming) number of Iranian dissidents. Vahidi is alleged to have bombed a Jewish cultural center in 1994. His selection is transparently an attempt to provoke Israel and its ally, the United States, two nations that are sinking fast, powers that are collapsing of their own weight and imperial ambitions, into rash actions.
If Israel bombs Iran, that will redeem Ahmadinejehad 's fanatic, vote-stealing, torturing ways (Iran's own Dick Cheney). Just like the British fell behind Churchill as London was blitzed, not out of love of Churchill but out of hate of their 'unsporting' (the Afghans' evocative phrase for the British who bombed Kabul post-WWI in an attempt to stem their own empire's ebb) enemy, Iranians will coalesce behind their cunning leader in the face of an Israeli blitz (for which Israel's strafing of Beirut in 2006 was a dry run). 
I am not in any way equating Churchill with Iran's hick figurehead. Only that nations that are blitzed do not react kindly to the destruction raining from the sky. 
And the international community will coalesce around Iran, of course. How could it not? Does a terrorist Defense Minister constitute a legitimate casus belli? Does NATO, already resentful that they are forced to help us police Afghanistan, want to express approval for an unprovoked (in the conventional sense) Israeli attack, or are they less eager for the Rapture than we are? (Mike Huckabee would love this attack, as would most of Congress, either Family members or wannabes, or Joe Lieberman and his ilk, or... Well, let's forget about the rest, crypto-Communists who hate America.)
Can American troops get out of the crossfire fast enough? Can the crippled American economy withstand the closing of the Persian Gulf? Would Iraq declare its solidarity with its strafed neighbor, and show Americans what a tragic farce the last decade of endless war has been? 
(It's a tragic farce anyway. But it could always be worse.)
