U.S., Israel Discuss Triggers for Bombing Iran’s Nuclear Infrastructure - The Daily Beast

U.S., Israel Discuss Triggers for Bombing Iran’s Nuclear Infrastructure - The Daily Beast: Matthew Kroenig, who served as special adviser on Iran to the Office of the Secretary of Defense between July 2010 and July 2011, offered some of the possible “red lines” for a military strike in a recent Foreign Affairs article he wrote.
