The centerpiece of the Bush administration's case for going to war in Iraq was Secretary of State Colin Powell's presentation to the U.N. Security Council on February 5, 2003, six weeks before the invasion.

Every lethal terrorist attack in the United States since 9/11 has been carried out by an American citizen or a legal permanent resident, not by recent immigrants or by refugees. So tamping down immigration won't fix the real issue, which is 'homegrown' terrorism.

On the 11th anniversary of 9/11, it is some consolation that the man most responsible for that terrible morning will not be smiling smugly to himself as satellite TV brings to the leafy boulevards of Abbottabad the somber images of New Yorkers commemorating those who perished in the Twin Towers.
