his command of a squadron.
19911993 Senate Select Committee on POW/MIA Affairs
Helped by McCain's efforts, in 1995 the U.S. normalized diplomatic relations with Vietnam
Since January 1993, McCain has been Chairman of the International Republican Institute, an organization partly funded by the U.S. Government that supports the emergence of political democracy worldwide.[97]
In October 2005, McCain introduced the McCain Detainee Amendment to the Defense Appropriations bill for 2005, and the Senate voted 909 to support the amendment.[167] It prohibits inhumane treatment of prisoners, including prisoners at Guantanamo Bay, by confining military interrogations to the techniques in the U.S. Army Field Manual on Interrogation.
Meanwhile, McCain continued questioning the progress of the war in Iraq. In September 2005, he remarked upon Chairman of the Joint Chiefs of Staff Richard Myers' optimistic outlook on the war's progress: "Things have not gone as well as we had planned or expected, nor as we were told by you, General Myers."[172] In August 2006, he criticized the administration for continually understating the effectiveness of the insurgency: "We [have] not told the American people how tough and difficult this could be."[149] From the beginning, McCain strongly supported the Iraq troop surge of 2007.[173] The strategy's opponents labeled it "McCain's plan"[174]
