The peace negotiations will be resumed after the Afghan elections are over and till such time the US will launch air strikes and military operations against the Taliban, whose leadership currently has been significantly weakened

The Taliban believes that such attacks will provide an opportunity for it to bargain from a position of greater strength and derive maximum concessions from the talks.
