IMO ...
Washington will normalize Indo-Pak relations and make the LoC a permanent border so India can focus on China. In return, Pakistan will get to flush India's influence in Afghanistan, and be the primary caretaker of Afghanistan moving forward.
US arms aside, I think we'll see a conversation about Pakistan building a noticeable presence in Afghanistan.
Everything from the ISI returning to Kabul to Pakistani aircraft flying overhead is going to be on the cards. Basically, whatever it takes for (1) Pakistan to feel secure, but (2) without hurting the Indians.
It's not so much about giving India hegemony, but to simply split South Asia into halves, and give one half to Pakistan (the west) and the other to India (east). That split is a border in Kashmir.
In return, the US can remove its forces out of the region yet still maintain influence in Afghanistan (via Pakistan).
This 'tweak' actually makes Pakistan's growing ties with Turkey a lot more logical now. The US can use Turkey to funnel whatever Pakistan needs (esp. US-origin technologies). So, the T129, the LM2500-equipped MILGEMs, the GE-equipped TFX, etc, does make sense under this framework.
