Nice post dinosaur, but the fact of the matter is that most of the Pukhtoons and Balochis are patriots of Pakistan and the idea of separation, though around, is limited. Sure there are groups, especially those functioning under pay of Karzai, who wish for Pukhtoons to separate from pakistan and join Afghanistan, but this will never happen. Pakistan's people, Puktoon, Balochu, Punjabi, Kashmiri, Sindis, and others would never let this happen. Not to mention that pakistani people are not an unintelligent people, they are resourceful and so far no leader has cultivated the patriotism and strength of Pakistanis to its full potential, but ti is very plausible that what we are seeing right now is a short era of instability, which I believe will be followed by a rapid revival of the state of Pakistan, but this willonly happen once the people exert themselves.
I enjoyed your post of the analysis of foreign countries seeing Pakistan as a threat and you are 100% right. Pakistan is a rleigious society, so foreignors wish to limit Pakistan's potential.
Inshallah, Allah swt will frustrate their ambitions against Pakistan.
Your ideas may be based on sincerity but alas they are not backed by the existance of any concrete steps for harmonus and mutually benificial relations between various ethnicities right from the first day of Pakistan's inception...that is why Bangalis walked out...and that why Baluch, Pashtun, etc. disillusionment with Pakistan.
You cannot consolidate such relations just by emotional slogans...it needs effective and practical measures...
