Twenty-eight American soldiers were killed in Afghanistan in June, making it the deadliest month for U.S. troops since the war in Afghanistan began in 2001. Much of the spike in violence is attributed to a resurgent Taliban and al-Qaida, both in Afghanistan and in neighboring Pakistan.
Richard Clarke, who has served as a top counterterrorism adviser to every president since George H.W. Bush, tells Linda Wertheimer more troops are needed in Afghanistan to turn the situation around, but the troops are tied down in Iraq.
He says there is once again an al-Qaida sanctuary along the Afghan border in Pakistan, where people are being trained by al-Qaida to attack western interests, including the United States.
"There is only so much the United States can do without the cooperation of the Pakistani government," he says. "Frankly, we're not getting that cooperation. There are still elements within Pakistani intelligence who are supporting the Taliban."
According to Clarke, the U.S. should strike a new deal with the Pakistanis, telling them "if you cooperate in ending this sanctuary with the Taliban, we will help you … but we cannot have a sanctuary for al-Qaida again."
