What i have learnt from history so far is that US make allies based on its own interest, once it has achieved its objectives it throws the ally under the bus. Currently US wants to use India to counter China and also wants a big piece of the Indian arms expenditure pie.
Comparing US with China for alliance is always a big mistake by some pakistanis. Do US has a neightbour called pakistan? No. Why would US care pakistan strive or not? But it cannot be say the same to China. Does a poor and undeveloped pakistan beneift far west of China? Do US has a economy route from pakistan to US? NO. China has, a route connected from indian ocean to west side of inner China. Why do u think China will abandon Pakistan like US?
True pakistanis , please do not trust any overseas pakistanis words. They are brainwashed to speak ill of China. Their action is meant to served their own personal benefit. If pàkistan is dead or not is not theirs business. They will be happily calling their adopted countries as their home.
