wish people could understand your question well
you remind me of @
VCheng here...
before we can answer this question we need to establish if they really failed or not?
by finding out who was talking to whom?
recall the comments like "its like brothers talking to brothers" said one emotionally cuffed Irfan sadique who considers Mullah Fazlullah a noble saint with a gem for a heart.
I dont think the talks failed , they were not among two adversaries but among the people who share the same faith and ideology (time & again expressed by nawaz league leadership, hail to the internet & countless private media sources that they cant retract & deny their statements) because both the Nawaz party and their long lost brothers achieved their objectives.so in short the talks finished once the objectives were achieved.
what objectives?
for TTP
rearm and regroup, get respite from the PAF raids on them when they were in a bit of a "pickle". TTP leadership called out to their brothers and Nawaz league was obliged to respond as requested. PAF ad Artillery strikes were called off while the body count of civilians and soldiers continued to mount.
For Nawaz League
another deep strike on its enemy i.e Pakistani military that the house of Sherif's wants to degrade, humiliate and suffer to a level that it becomes a shadow of its former self. Musharaf's trial is a sideshow and a smoke scream.
the rants of the Nawaz league Hawks from the recent past and present are very much clear who is their intended target its the military.
and what better way to get revenge in the form of severed heads and blown up bodies from the ideologically similar brothers who have declared war on Pakistani state and its constitution unislamic & irrelevant.
Now it will be business as usual as long as the TTP goes "easy" on Punjabi parts of the country that houses the vote bank for the Sherif density to rule Pakistan for the time to come.
Nawaz is laughing, he is laughing his *** off right now. because as his brothers will start the cull of the Pakistani population.... a set group of analysts, anchors, writers and specific media channels will open their guns on Pakistan military as well. blaming it for failing to defeat the terrorism and its decision to join Americans war on terror.
