The president just announced that:
This year, I will work with Congress and our military to finally repeal the law that denies gay Americans the right to serve the country they love because of who they are.
This is strong move, but in line with more and more military leaders and experts. Just today former Chairman of the Joint Chiefs of Staff, General John Shalikashvili released a statement saying:
“Don’t ask, don’t tell” was seen as a useful measure that allowed time to pass while our culture continued to evolve. The question before us now is whether enough time has gone by to give this policy serious reconsideration. I believe that it has.
... Studies have shown that three-quarters of service members say they are personally comfortable around gays and lesbians. Two-thirds say they already know or suspect gay people in their units. This raises important questions about the assertion that openly gay service would impair the military. In fact, it shows that gays and lesbians in the military have already been accepted by the average soldier.”
In 2008, a bi-partisan panel of retired General and Flag officers carefully reviewed this matter for a year and concluded that repeal would not pose a risk to the military's high standards of morale, discipline, cohesion, recruitment, or retention
In addition, an article in Joint Force Quarterly (which was incidentally reviewed by Adm. Mullen’s office) this September arguing forcefully for repealing the policy –saying that there is no evidence that repealing the policy will negatively affect unit cohesion –won the 2009 Secretary of Defense National Security Essay competition. Even Colin Powell, former Chairman JCOS and former Republican Secretary of State thinks that the policy should be reviewed. It is a promising sign that the president is making such a strong move on the policy saying: "Its the right thing to do."
