Gregg Easterbrook, who was raked over the pitiless coals of the blogosphere last year, has a really good piece at his New Republic blog; an alternate history of the past two and a half years, as it might have been if President Bush had launched a preemptive attack on Al Qaeda before September 11: An Alternative History.

Washington, April 9, 2004.

A hush fell over the city as George W. Bush today became the first president of the United States ever to be removed from office by impeachment. Meeting late into the night, the Senate unanimously voted to convict Bush following a trial on his bill of impeachment from the House.

Moments after being sworn in as the 44th president, Dick Cheney said that disgraced former national security adviser Condoleezza Rice would be turned over to the Hague for trial in the International Court of Justice as a war criminal. Cheney said Washington would “firmly resist” international demands that Bush be extradited for prosecution as well.

On August 7, 2001, Bush had ordered the United States military to stage an all-out attack on alleged terrorist camps in Afghanistan. Thousands of U.S. special forces units parachuted into this neutral country, while air strikes targeted the Afghan government and its supporting military. Pentagon units seized abandoned Soviet air bases throughout Afghanistan, while establishing support bases in nearby nations such as Uzbekistan. Simultaneously, FBI agents throughout the United States staged raids in which dozens of men accused of terrorism were taken prisoner.

Reaction was swift and furious. Florida Senator Bob Graham said Bush had “brought shame to the United States with his paranoid delusions about so-called terror networks.” British Prime Minister Tony Blair accused the United States of “an inexcusable act of conquest in plain violation of international law.” White House chief counterterrorism advisor Richard Clarke immediately resigned in protest of “a disgusting exercise in over-kill.” …

Bush justified his attack on Afghanistan, and the detention of 19 men of Arab descent who had entered the country legally, on grounds of intelligence reports suggesting an imminent, devastating attack on the United States. But no such attack ever occurred, leading to widespread ridicule of Bush’s claims. Speaking before a special commission created by Congress to investigate Bush’s anti-terrorism actions, former national security adviser Rice shocked and horrified listeners when she admitted, “We had no actionable warnings of any specific threat, just good reason to believe something really bad was about to happen.”

Of course, some people on the left side of the aisle are now eager to make this scenario come true—even after September 11.
