I folly of your logic is around China. Pakistan today is moving towards becoming a proxy of China against India as it was of US against USSR. And we know how that went down.. Its the single minded dependence on China (IPC pipeline, Gwadar, Jf -xx, Al khalid, KKh, Combined diplomacy etc..) that is the biggest variable for Pakistan's future. Take China away and suddenly Pakistan's most options just vanish. I know its not gonna happen, but how oftern do you see a nation really growing by being so dependent on another nation..
I don't think China needs proxies against India. It is taking India on directly in the Indian ocean, on the northern border and in international fora by blocking India access to aid.
And Pakistan is not singularly *dependent* on China. It is most definitely a relationship that has withstood the test of time for five decades and will continue to go from strength to strength as Pakistan and China share regional and international perceptions almost to a T. That said, Pakistan has excellent relations with countries as diverse as Turkey, Ukraine, South Africa, UAE, Saudi Arabia, Malaysia, Indonesia, Iran etc. etc. On that last one in particular, despite Indian maneuvering, why did Iran agree to eject India from the IPI and still continue building the pipeline? Not due to a stellar success of Indian diplomacy, I would guess.
Afghanistan is another element of Pakistan's foreign policy that hasn't involved China much. We have navigated our relations with the west in a positive way, in my opinion. We don't always see eye to eye, but we have positioned ourselves effectively, to mutual benefit, and have participated - and continue to participate - in various alliances with the West over the past 60 years. Yes, we have those periods now and then where we call each other names - but the French and the Americans do that to each other all the time too - it doesn't change the fact that high level cooperation exists between Pakistan and all the major western players. In fact, the whole undercurrent of this thread is that India is giving in to US pressure in returning to the negotiating table with Pakistan.
Now, short of questioning our intent in these relationships - which is a pointless subjective discussion - I think they highlight your assertion regarding Pakistan being solely dependent on China to be false.
Some of the most significant projects going on in Pakistan today, such as the UAE/Pakistan Khalifa refinery ($1.5B project - will add 30% to Pakistan's refining capacity), the expansion of the Pak-Arab refinery, rail modernization and highway projects with Turkey etc. etc. and the list goes on, are with countries other than China. The ruling family of UAE has God-knows-how-many palatial residences in Pakistan, a country they have always considered a second home. How many do they have in India? Almost all the armed forces in the middle east, save Iraq and Egypt, have had Pakistani trainers and even officers directly commanding their troops. The Indonesians were the ones who offered to send a naval flotilla to help Pakistan in 1965 and our relations continue to be very strong with them. So, please, let's not make assertions that fly in the face of reality.
It is a massive underestimation if you honestly believe that Pakistan's diplomacy has yielded excellent relations only with China.
