Former President George W. Bush is worried the U.S. might pull out of Afghanistan too early to the detriment of that country's women.

In an interview with Fox News that aired Thursday, Bush warned that Afghan women will "suffer" should the Obama administration decide to downscale troop levels there.

"My concern of course is that the United States gets weary of being in Afghanistan and says 'It's not worth it, let's leave' and Laura and I believe that if that were to happen, women would suffer again," he told Fox's Greta Van Susteren. "And we don't believe that's in the interest of the United States or the world to create a safe haven for terrorists and stand by and watch women's rights be abused."

"We liberated Afghanistan from the Taliban because of providing a save haven for al Qaeda," he continued. "But I ablative then and believe now we have an obligation to help this young Democracy to survive and thrive."

Bush's comments came the same day he and former first lady Laura Bush kicked off a two-day conference at Southern Methodist University focusing on women's rights issues in Afghanistan – an issue Mrs. Bush also championed when she was in the White House.

"Isolationism will end up subjecting certain people to horrors that I don't see how our country can live with that kind of decision," the former president also said.

The Obama administration has said that it will gradually hand off responsibilities to Afghanistan security forces as it draws down U.S. troops between this summer and the end of 2014.

But a Government Accountability Office report issued in January questioned whether the centerpiece of the Obama administration's exit strategy for Afghanistan - a training program for Afghan security forces - can deliver as promised.

A CNN/Opinion Research Corp. poll in February indicated six in ten Americans are opposed to the war.
