Military options, when it comes to Iran, are “vastly premature,” says Brian Katulis, a senior fellow at the Center for American Progress. Katulis argues that if the the United States wants the best possible option, it should stay its course and focus on diplomacy.

“The main focus is to use diplomacy combined with economic sanctions to try to change the calculus of the regime in Tehran. And I think it’s important to give this diplomacy some time to work, because any talk of military options, at this point, is vastly premature,” says Katulis.

Pivoting toward a more hostile position will only strengthen Iran’s hard-liners, drive up the price of oil and hurt American consumers, he says.
