A federal judge in Manhattan has ruled that Iran was complicit in the 9/11 attacks. Among the thousands killed in the terrorist strikes were more than a dozen Bucks County residents.  The judge, who received affidavits from members of the 9/11 Commission and three Iranian defectors, made the decision in a lawsuit filed on behalf of some of those Philadelphia area families, and others.

The decision is shocking, said University of Pennsylvania political science professor Ian Lustick.

"This is a major political statement and for the judge to establish it as accepted fact, or to claim that is, is to me shocking," Lustick said. "I know of no significant evidence that Iran was involved that has been advanced seriously."

Lustick said he doubts this case will set precedent. But he said he's concerned it could stoke the fires for a U.S. military strike against Iran.
