Today, NSN Advisory Board Chairman Les Gelb responded to Republican criticism of President Obama's measured response towards the unfolding situation in Iran:

"Republican leadership calls for Obama to condemn Iran's election results and speak out for the demonstrators shows no knowledge of Iran whatsoever. If he did so, America would become the issue in Iran, not Ahmadinejad, and we would become the excuse and justification for spilling Iranian blood.

"These sniping remarks by Republican leaders also shows they put pandering to their right wing above American national security. Why can't they listen to their own real foreign policy expert -- Senator Richard Lugar -- and see and say that the U.S. must exercise restraint in our public statements for Iran's sake and our own."

Les Gelb is a former NY Times columnist and former senior government official.
