Right now, the thing which makes America more paranoid and insecure than anything is China. PoK is right now part of a grand scheme which will effectively give china "two coastlines" and will form part of its most vital energy corridor. America and India have seen eye-to-eye on several issues so far, but there are even more which could be endorsed. America is also wary of the fact that China bordering Pakistan via PoK is a great strategic benefit to China. Not to mention that us holding PoK would allow us to border A'stan - something which US wants a lot for its efforts there, as we are more reliable than Pak If we control PoK, we have China's IOR maritime energy by the balls - what more could the US ask for?
