To demonstrate its good faith in defense of international norms and legality, the United States must hold its own officials and patrons to account. Mr. Obama and the US system of justice lose all credibility on the issue of chemical weapons use by refusing to acknowledge the history of criminal behavior widely alleged to have occured under prior administrations. To avoid further illegality and confusion on these essential points, Mr. Obama must immediately draw a bright line between the conduct of his administration and those that have acted without regard to the world's established humanitarian, legal, and strategic norms.
