Argument: Gay soldiers do not undermine unit morale and cohesion
John Shalikashvili. "Second Thoughts on Gays in the Military". New York Times. January 2, 2007 - "Last year I held a number of meetings with gay soldiers and marines, including some with combat experience in Iraq, and an openly gay senior sailor who was serving effectively as a member of a nuclear submarine crew. These conversations showed me just how much the military has changed, and that gays and lesbians can be accepted by their peers. [...] This perception is supported by a new Zogby poll of more than 500 service members returning from Afghanistan and Iraq, three quarters of whom said they were comfortable interacting with gay people. [...] I now believe that if gay men and lesbians served openly in the United States military, they would not undermine the efficacy of the armed forces. Our military has been stretched thin by our deployments in the Middle East, and we must welcome the service of any American who is willing and able to do the job."
Adm. Mike Mullen, the chairman of the Joint Chiefs of Staff, says that "after a careful examination, there is no scientific evidence to support the claim that unit cohesion will be negatively affected if homosexuals serve openly."
Former Senator and Secretary of Defense William Cohen spoke against the policy publicly in early January 2007: "I now believe that if gay men and lesbians served openly in the United States military, they would not undermine the efficacy of the armed forces."
