Next tonight, Afghanistan, where both the U.S. and Afghan governments are exploring new negotiations with the Taliban.Margaret Warner sat down with three Afghan women who have a significant amount at stake in the outcome.We don't see the real inclusion. We don't see the real sort of participation of us.These women are influential figures in Afghanistan in politics, business and non-governmental organizations.That's a far cry from the subordinate role women held in Taliban era Afghanistan, barred from schools and most jobs and brutalized for social infractions.They were in Washington last week meeting with senior members of the administration and Congress. Their message?Women's voices must be heard as the U.S. and Afghan governments chart the course ahead. Their visit came at a crucial time. The summer fighting season against the Taliban has reached a fever pitch.Yet the administration and President Hamid Karzai's government are stepping up efforts to talk to the Taliban, including figures reportedly close to Mullah Omar, seeking a negotiated end to the 10-year-old war.What's more, President Obama is on the verge of announcing how many U.S. troops he will begin withdrawing from Afghanistan next month.At a White House meeting, Lt. Gen. Doug Lute, the president's point man on Afghanistan, told the women the troop decision will be made in a thoughtful manner.
