An international summit on combating militants from the Islamic State has opened in France, bringing together around 30 countries from a U.S.-led coalition. The Obama administration says several Arab League countries have signed on for airstrikes in Iraq and Syria, but no sustained campaign is imminent. President Obama has already asserted he does not need approval from the Congress to expand U.S. airstrikes into Syria. On Friday, the Obama administration says it derives legal authority for the war on the Islamic State from both the 2001 war on terror resolution as well as the 2002 vote authorizing the Iraq War. The White House made the claim despite President Obama’s previous call for repealing the war authorization measures. On Saturday, video was posted online showing a member of the Islamic State beheading British aid worker David Haines, the third Western hostage to be beheaded by the militants in less than a month. In the video, the Islamic State issued death threats against another captive British aid worker, Alan Henning. We are joined by Phyllis Bennis, a fellow at the Institute for Policy Studies.
