The divergence of the US’ and Pakistan’s interests is part of a decades-long trend, that will only play out over time. But is the US now willing to just hand Pakistan over on a plate to an all-too-eager China? That doesn’t seem likely. The US still needs its supply lines into Afghanistan open to keep up its presence there, and it needs Pakistan to keep them that way. It also needs Pakistan’s help in counterterrorism, the little it is willing to give.
The US ceding Pakistan to China would mean handing its expansionist geopolitical rival a strategic win in a region of crucial importance to its own interests, and as isolationist as the Trump administration may be, a tweet and another round of withheld aid doesn’t a policy shift make.
