More than two years after the U.S. left Iraq, the country is falling into chaos and threatening to pull the Obama administration back into the conflict. Parts of Iraq including Mosul in the north and much of Anbar Province in the west are now under control of ISIS, or the Islamic State in Iraq and Syria. Meanwhile political leaders in Baghdad are struggling to keep the country together. “Losing Iraq,” a new PBS Frontline report airing Tuesday on SDPB-TV, explores how events reached this point. It explores the U.S. role in Iraq from the 2003 invasion to the current crisis. Mike Wiser is co-producer/writer of “Losing Iraq." He joined Dakota Midday and discussed the Frontline documentary.
