Jamie Fly and Gary Schmitt argue "The Case for Regime Change in Iran."
It has been the policy of U.S. presidents over the last three decades to state that a nuclear-armed Iran is unacceptable. Yet as Iran moves closer to achieving that goal, political leaders, including key Obama administration officials such as Secretary of Defense Leon Panetta, have begun to waver. They now speak more frequently about the potentially disastrous consequences of an Israeli or U.S. military strike on Iran's nuclear program than about the dangers of a nuclear Iran.
Matthew Kroenig thus deserves credit for advancing the argument that the repercussions of a military attack on Iran's nuclear program are a worthwhile risk, given the far more dangerous consequences of Iran getting the bomb ("Time to Attack Iran," January/February 2012). There are, however, problems with Kroenig's strategy for avoiding the nightmare scenario. Namely, a limited military strike would only be a temporary fix, and it could actually do the opposite of what it intends -- drive the program further underground and allow Iran to retain the ability to threaten the United States and its allies.
If the United States seriously considers military action, it would be better to plan an operation that not only strikes the nuclear program but aims to destabilize the regime, potentially resolving the Iranian nuclear crisis once and for all....
The Obama administration has avoided the choice between a military operation and a nuclear Iran -- relying on the U.S. intelligence community's conclusions that Iran has not made the final decision to develop a weapon. But if history is any guide, its faith in receiving any intelligence to the contrary in a timely and unambiguous way is misplaced. Kroenig is correct then to argue that a military strike should be in the cards. But he is wrong to suggest that a limited strike is the only one that should be on the table. If strikes are chosen, it would be far better to put the regime at risk than to leave it wounded but still nuclear capable and ready to fight another day.
Whole thing here.
