How’s "reconciliation" with the Taliban working out?

Burhanuddin Rabbani, former Afghan president and chair of the body tasked with making peace with the Taliban, has been assassinated. 

Two Taliban commanders came to meet with Rabbani, reportedly bearing a "special message" for him from the Taliban. As one embraced Rabbani, he detonated a bomb hidden in his turban, killing them both and wounding Masoom Stanakzai, a senior advisor to Rabbani.

The fact that Stephen Lewis, among others, says negotiating with the Taliban is now "conventional wisdom" doesn’t make the tactic any less absurd.
