Evidently the lunatic fringe is a big tent. Even some erstwhile respectable commentators on the right have wandered under its canopy. Here, for example, is former Assistant Secretary of the Treasury and former contributing editor at National Review Paul Craig Roberts waxing delusional about how George Bush will fabricate a pretext to attack Iran with nuclear weapons:
[A] low yield, perhaps tactical, nuclear weapon will be exploded some distance out from a U.S. port. Death and destruction will be minimized, but fear and hysteria will be maximized. Americans will be told that the ship bearing the weapon was discovered and intercepted just in time, thanks to Bush's illegal spying program, and that Iran is to blame. A more powerful wave of fear and outrage will again bind the American people to Bush, and the U.S. media will not report the rest of the world's doubts of the explanation.
There's more evidence of Roberts' slide into nuttery at the link. It's very sad.
