Biden's in no hurry to do anything.
Right now, his immediate foreign policy priority are China and India. To the US, Afghanistan is already a done deal. Much like I predicted months ago, Biden will delay the pullout, but he's already said he's gonna pullout completely before the end of the year. In other words, the US no longer feels it needs Pakistan, other than pulling out its troops, and even then it feels it can strong arm Pakistan into continuing to use Pakistan's gloc and aloc freely.
No matter how much PTI wants to pretend otherwise, the US not inviting Pakistan to the climate summit, and skipping over Pakistan to visit India and BD, are both a major snub.
Biden is now looking to strengthen ties with India and QUAD as a whole. Biden is also looking to go after China even harder than Trump. A lot of people called Trump protectionist, and he certainly was, but Biden is in many ways even more of a protectionist than Trump will ever be.
With Pakistan moving towards neutrality, the US wants nothing to do with Pakistan. Just like how the US only partnered with Pakistan during the cold war after joining the western-bloc, so to will the US move away from Pakistan, once Pakistan leaves and becomes a neutral nation once again. The US doesn't deal with neutral nations all that well.
On a side note, Biden is already making multiple major mistakes. Its clear that for all the information that US intelligence provides him, he does not know how to run successful foreign policy. I believe even a former Obama official called him a failure when it comes to foreign policy.
