On January 10, 2007, Bush announced the commitment of more than 20,000 additional troops as a part of the Iraqi troop surge of 2007. McCain was a leading advocate for the move, leading some Democrats to call the policy the "McCain Doctrine". Days after the announcement, McCain appeared on CBS' "Face the Nation" and said, "This is a chance under the new leadership of General Petraeus and Admiral Fallon to have a chance to succeed. Do I believe it can succeed? Yes, I do." On February 4, he criticised a bipartisan non-binding resolution opposing the troop buildup, calling it a "vote of no confidence" in the US military. The next day, McCain said, "I don't think it's appropriate to say that you disapprove of a mission and you don't want to fund it and you don't want it to go, but yet you don't take the action necessary to prevent it". McCain's April 11, 2007, speech on Iraq was delivered to the Virginia Military Institute Corps of Cadets after his return from Iraq. He supported a new strategy in Iraq and opposed Democratic efforts towards troop withdrawal. McCain repeated his criticism of the Bush administration's handling of the Iraq War on April 29 in Elko, Nevada, and stated that Rumsfeld would be remembered as "one the worst secretaries of defense in history". On September 19, 2007, McCain voted against requiring minimum periods between deployments. In November 2007, on the Charlie Rose show on PBS, Rose asked if South Korea might be an analogy of where Iraq might be, in terms of an American presence, over the next 20 to 25 years. McCain replied that he didn't think so – even if there were no (ongoing) casualties, saying "I can see an American presence for a while. But eventually I think because of the nature of the society in Iraq and the religious aspects of it that America eventually withdraws. On January 3, 2008, at a campaign stop in Derry, New Hampshire, when a questioner said, "President Bush has talked about our staying in Iraq for 50 years," McCain responded:  In March 2008, McCain said of Iraq and terrorism that "Gen. Petraeus is correct when he says that the central battleground in the struggle against al Qaeda is Iraq and Osama bin Laden just confirmed that again with his comments last week." In April 2008 he said, "There are tough decisions ahead and America deserves leaders that are up to the challenge. As president, I will ensure that our troops come home victorious in this war that is part of the larger struggle against radical Islamic extremism and will continue to make keeping our nation secure my highest priority."
