That's why the prime minister needs to weave a vision where Pakistan is the only regional partner that can maintain the peace and allow them to realize what a trillion dollars of sunk costs could not; a peace domain in which to invest, and reap the benefits.
Trump loves a good native, make sure to make large posters with large dollar signs on it; $ billion can be from this project, and $ billion from this project. A US export facility in Karachi port, a US warehousing and processing facility in Quetta, a $ Billion US Ore Processing facility in Kandahar, and so on and so on. Especially if he see US companies competing with China and getting a slice of the action. He's a "Big Picture" kind of guy. Show him glitz and glamour, and he's in. Lithium mining has huge potential, but only through a friendly corridor.
We also need to be careful that some elements will start to push for Baluchi independence, or Sindhi independence, or renegotiating the Durand Line. Furthermore, Pakistan's Nuclear weapons are not to be discussed. Pakistan has had them for over 35 years, and knows how to keep them secure. It maintains the peace in the region and provides the umbrella for focusing on economic development rather than a conventional arms buildup beyond what is minimally necessary. The Prime Minister has to hold on getting the US to partner in preventing any thought of those ideas. A Stable and territorial intact Pakistan will be a strong and stable partner in the region, for peace, trade, and prosperity for both nations and the world.
