U.S. Sen. Dick Durbin (D-Ill.) supports the move to send military advisers to Iraq, but says there’s only so much the U.S. can do to stop that country’s crisis. Durbin is in favor of sending a limited number of personnel to Iraq to protect the U.S. Embassy in Baghdad, and to advise the Iraqi military on stopping the advance of militant groups. But Durbin wants that to be the limit of their involvement. “It’s not the capacity of the American military to try to make the Iraqis feel that their nation is more important than the war they have with their neighbor over religion, and it’s not within the capacity of the American military to end a debate over the future of the Islamic religion that has been going on for 13 centuries,” Durbin said. The conflict Durbin is referencing is between the major two denominations of Islam: Sunni and Shia. Sunni militants known as the Islamic State of Iraq and the Levant are fighting the Iraqi government, while Iraq’s current prime minister, Nuri al-Maliki, is Shiite. U.S. Secretary of State John Kerry and President Obama have emphasized that there are no plans to deploy American ground troops back into Iraq.
