A Bahraini anti-government protester steps on a caricature of U.S. President Barak Obama on an anti-U.S. sign containing images of Syrian and Bahraini flags during a protest Thursday, May 17, 2012, in Diraz, Bahrain, against a recent U.S. administration decision to permit the sale of some arms to Bahrain. Leaders of Bahrain's pro-democracy movement have criticized the United States for taking a tough stand against Syria's leadership and a milder approach when dealing with the Bahraini monarchy.
