of Obama's presidency. Gates was the fourteenth Cabinet member in history to serve under two presidents of different parties, and the first to do so as Secretary of Defense. One of the first priorities under President Barack Obama's administration for Gates was a review of U.S. policy and strategy in Afghanistan. Gates, sixth in the presidential line of succession, was selected as designated survivor during Obama's inauguration. On March 1, 2009, he told David Gregory on Meet the Press that he would not commit to how long he would serve as Secretary of Defense but implied that he would not serve the entire first term. While Gates continued the troop withdrawals in Iraq, which already had begun in the Bush administration, he also implemented a rapid, limited surge of troops in Afghanistan in 2009. Robert Gates removed General David D. McKiernan from command in Afghanistan on May 6, 2009 and replaced him with General Stanley A. McChrystal. The Washington Post called it "a rare decision to remove a wartime commander". The Washington Post described the replacement as one of several replacements of generals who represented the "traditional Army" with generals "who have pressed for the use of counter-insurgency tactics". In December 2009, Gates visited Afghanistan following President Barack Obama's announcement of the deployment of 30,000 additional personnel against the Taliban insurgency. Time magazine notes that Gates and U.S. Secretary of State Hillary Clinton have "forged a formidable partnership", speaking frequently, "comparing notes before they go to the White House", meeting with each other weekly and having lunch once a month at either the Pentagon or the State Department. In a March 2010 speech to a NATO conference in Washington, Secretary Gates said that "The demilitarization of Europe—where large swaths of the general public and political class are averse to military force and the risks that go with it—has gone from a blessing in the 20th century to an impediment to achieving real security and lasting peace in the 21st". Gates announced in February 2010 that the department would lift its ban on women serving on submarines. Gates also prepared the armed forces for the repeal of the don't ask, don't tell policy. Since the repeal in 2010, homosexuals are able to serve in the military openly. In service of that goal, he announced in late March 2010 the approval of new regulations that would make it more difficult to kick
