Nunn: Pakistan Is Our Most Dangerous Conflict

Speaking at the Aspen Ideas Festival last week, former Sen. Sam Nunn warned that while the world is focusing on Iraq and Afghanistan, Pakistan was the "most dangerous and most difficult" security situation facing the United States. During the same panel, former Secretary of State Colin Powell said that the next President -- whether McCain or Obama -- would have to continue drawing down forces because "the U.S. cannot sustain this level of deployment indefinitely."

Nunn and Powell also touched on other topics, including the "Don't Ask, Don't Tell" policy which both men helped craft. While Nunn said he was proud of the gays and lesbians who have served, he declined to endorse a repeal of the policy. Powell agreed.
