Talk about a U.S. attack on Iran appears to be growing louder in Washington. There are reports that Vice President Dick Cheney’s office has issued instructions to conservative think tanks to start a drumbeat for attacking Iran. On Monday, the American Enterprise Institute is hosting two events related to Iran. Former House Speaker Newt Gingrich is giving a speech on how the war on terrorism should be viewed as “a world war that pits civilization against terrorists and their state sponsors who wish to impose a new dark age.” Later in the day former CIA Director Jim Woolsey and others will meet to discuss a new book by longtime Iran hawk Michael Ledeen titled “The Iranian Time Bomb: The Mullah Zealots’ Quest for Destruction.” The Heritage Foundation recently hosted an inter-agency Bush administration war game attempting to anticipate Iranian responses to a U.S. bombing campaign. Meanwhile, The Sunday Times of London has reported the Pentagon has drawn up plans for massive air strikes against 1,200 targets in Iran, designed to annihilate the Iranians’ military capability in three days. The main source of the article was an official at another conservative Washington think tank, the Nixon Center.
