Teflon Resignation
I'm just a student, so you'll have to salt these ideas yourself. IMO, Perle leaving is no big thing.
It doesn't seem there is much scandal at the moment to force his resignation. My guess, it may be a pre-emptive(!) resignation, to keep Bush/Cheney public images intact as things unravel.
If the war goes sour, or if PR issues come up, the current officials can blame the architect of the Whole Nasty Plan, and say he's already left. Teflon for war protestors.
The bulk of his work is done. The plans are written, approval is won, so no reason to stick around to see what happens now. Slip out the back, Jack.
No facts here, that's just my gut feeling -- after being thumped!

"Mr Perle has been a Washington insider since the early 1970s, is a personal friend of the Israeli Prime Minister Ariel Sharon, a fellow of the influential right-wing think tank the American Enterprise Institute, and chief proponent, along with the Deputy Defence Secretary, Paul Wolfowitz, of a pre-emptive foreign policy aimed at rogue states."

Perle wrote in his resignation letter that he could not ''quickly or easily quell criticism'' in the Global Crossing controversy, adding that it was ''based on errors of fact.'' Nonetheless, he wrote, ''I would not wish to cause even a moment's distraction from'' the war effort.

"It's not sufficient. It's cosmetic," said Larry Noble, executive director of the Center for Responsive Politics, of Mr Perle's move this week. "The fact that he's still on the board means there's still a conflict."

... he earned a nickname he appears rather to enjoy - "Prince of Darkness" - by opposing detente and arms control and promoting President Reagan's proxy wars in Nicaragua and El Salvador. In this administration, he is the ringleader and, with Paul Wolfowitz, Mr Rumsfeld's deputy, intellectual backbone of the the neo-conservatives who believe invading Iraq is the lever to remake the entire Middle East in America's image and interest. This grand design of almost Napoleonic sweep can be disavowed by the Bush people on the grounds that Mr Perle is (or was) a mere adviser.

Michael Ledeen, an A.E.I. scholar on the same panel, called Iraq "just one battle in a broader war. Iran is . . . the mother of modern terrorism."

... [Perle] suggested it was the work of a leftwing conspiracy. "I'm beginning to think that people who've been saying on the internet that I am part of a small neo-conservative cabal that runs the world actually believe what they are saying," he told the Financial Times.
