Some of the nation's most elite colleges are moving toward welcoming ROTC units back to campus in light of plans to repeal "don't ask, don't tell," the policy barring gays from serving openly in the U.S. military.

ROTC units disappeared from Yale, Harvard, Columbia, Stanford and other elite schools during the Vietnam era.

But it's far from certain the military will return to these colleges. The prospect of renewed campus debates on the topic also could expose antimilitary sentiment some suspect lurked beneath opposition to "don't ask, don't tell."
