After years of sitting back and letting Congressional authority to declare war transfer to the Executive Branch, it appears that some leading Members of the House and Senate are finally waking up to the consequences of their failure. On February 27, the House Progressive Caucus and the House Liberty Caucus joined forces to hold a hearing on the illegal wars raging in Afghanistan, Syria, Yemen and Iraq, demanding that Congress take back the war powers authority. The succession of regime change wars of the post 9/11 period have all been justified by the Authorization for the Use of Military Force (AUMF) that was passed in the immediate aftermath of the attacks on the World Trade Towers and the Pentagon.
