The Islamic State Tries to Ward Off U.S. Intervention in Iraq

The Islamic State has grown and thrived due to the largesse of the Sunni sheikhs and the absence of U.S. pressure on the group. As the United States began to offer measured support to the Iraqi government, the group formerly known as the Islamic State in Iraq and the Levant launched a propaganda campaign threatening the United States with violence if it intervened. While the group's ability to back up its threat is limited, a terrorist attack on the U.S. homeland by the group or a grassroots sympathizer could bring the full wrath of the United States down upon the militants, shattering any slim hope of re-establishing the caliphate.
