There is a degree of truth in your post.
The problem is peace in Afghanistan does not do away with the threat of India shutting off our water supply and then marching on to fulfill akhand bharat fantasy.
SMQ basically said don't expect us to do/achieve anything in regards to Kashmir. No other leader has made such a stupid statement about Kashmir in past.
Pakistan is playing the right cards. The ultimate issue is Afghanistan. The Indians are sh!tting their pants right now.
Just do not let the emotions get the best of you. Pakistan is an extremely powerful state and knows the weaknesses of its opponents. The regional states know this fact well and only the "smaller" regional states want the war in Afghanistan to continue.
