If there is anything substantive to this assertion the Democrats will jump all over it and use it to smear this administration. If they do nothing with it, I suggest we can safely assume it doesn't have "legs".
On ZULU's point, I agree that overturning the rule in Iran is a necessary part of winning the war on terror. The short-sighted previous policies tried to fight terror like crime, on a case-by-case basis --- but terrorism is ideological and must be won by pulling up the roots as well. IMHO, terrorism cannot gain steam in a Democracy which supports individual liberty.
Which way would you "overturn the rule"? Would you force secularization of the system by eliminating the supervisory religious bodies and imposing the sepration of religion and state, while preserving the parliament and elections? Or would you suppress the parlamentary system and restored to power pro-Western dictatorship (which had control under shah)?
