"As we said before, as long as the invader forces are in Afghanistan, we won't participate in any negotiations," Taliban spokesman Qari Mohammad Yousuf told the Pakistan-based Afghan news agency, AIP, Monday.
Yousuf also denied reports that negotiations had taken place between the Taliban and the Afghan government in Saudi Arabia.
My naive analysis: they see the possibility of the Iraq war coming to an end and are getting antsy at the possibility of being the center of attention.
