After inflicting heavy losses on weakened Afghan security forces a year ago, the Taliban under new leadership have been surprisingly slow to ramp up attacks at the midpoint of the traditional fighting season, senior American military officers said Sunday, July 17, according to the Associated Press.

In an Associated Press interview, Marine Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, said he is cautiously encouraged by a relative slackening of the Taliban's aggressive tactics.

Citing "a lower level of violence from the Taliban than we have seen in the past," Dunford was quick to say that while he believes Afghan forces have seized battlefield momentum, there are no assurances that the balance won't shift again.

"We've seen peaks and valleys with the Taliban before, but certainly on the ground right now the Afghan forces have the momentum," he said, speaking aboard an Air Force C-17 transport plane en route from Bagram Air Base in Afghanistan to Stuttgart, Germany. Dunford spent three days in Afghanistan speaking with U.S. and Afghan commanders, troops and officials. On Sunday he met with President Ashraf Ghani and other senior members of Ghani's government in Kabul.

Dunford commanded all U.S. and coalition forces in Afghanistan from February 2013 to August 2014, AP says.

In separate interviews in Afghanistan over the weekend, other senior U.S. officers highlighted an unexpected easing of Taliban military pressure in the days since Ramadan, the period of traditional Muslim fasting, ended in early July. One called it a "tactical pause," another said it points to a weakening of the Taliban, but none claimed it means an early end to the long war.
