Will try to make this better sentence by sentence.

Topic : APC and latter linked developments.

All Parties Conference - APC, initiated by the Prime Minister, ended up with a consensus which was to start talks on the table with the leadership of the Pakistani Talibans.
Initiated by the Prime Minister, the All Parties Conference (APC) concluded with a consensus to start talks with the Pakistani Talibans on the table.


PTI Chairman, Imran Khan, also joined the APC, after his demand of separate talks with PM and Army Chief was fulfilled.
After his demand of separate talks was fulfulled, Imran Khan, the Chairman of Pakistan Tehreek Insaaf (PTI) also took part in the APC.

However, even after the welcoming statement from the leadership of TTP, an attack was observed in the Upper Deer area which killed the Leutinent General of Pakistan Army.

Adding more to the fire, (the) TTP wasted no time in taking the credit (for) the attacks. Following this notorious event by the TTP, some major developments took place resulting in an angry speech by General Kiyani. PTI chairman Imran Khan, who had previously been a staunch advocate of peace talks changed his stance. PTI ideology of negotiations are now conditioned to the acceptance of the constitution of Pakistan and ceasefire.

I think APC on the first place was baseless, providing no line of action. It talked about the peace talks but failed to define the strategy, as to, what will be the subject of the negotiations?, To whom and how the talks would be done ?, and to what extent the Government would show flexibility? Prime Minister, Mian Muhammad Nawaz Shareef got a great chance of finalizing the matter to its fuller extent as all the political parties and establishment on board were willing to negotiate.

Nevertheless, TTP made the situation worse and jeopardized the talks. After these events, the government should now change its line of action.

Pakistani Government should now put obligations on TTP to surrender. The TTP should also accept the constitution of Pakistan and guilt on their part in case of any future attacks between or after the peace talks.


COMMENTS:

1. Definite need of improvement in grammar.
2. Overall, the article fails to apply a compelling argument, leading the reader to believe that it was written in haste.
3. Need to incorporate the usage of 'The', commas and full stops.

All the best.
