It's been a volatile period in the Middle East, with the U.S. and Iran trading threats and attacks. In just the last few weeks, an American contractor in Iraq was killed in an attack the U.S. blamed on an Iran-backed militia; the U.S. responded with airstrikes in Iraq that killed at least 25 fighters; hundreds of Iran-backed militiamen and their supporters held violent protests at the U.S. Embassy in Baghdad; and a U.S. airstrike in Iraq killed a top Iranian general, setting off massive protests and a retaliatory strike by Iran. We'll discuss the latest on this conflict, the history behind it, and what's at stake for U.S. foreign policy in the region. Original Air Date: Jan. 13, 9:30 a.m.
