While buying that strip of land makes sense for Pakistan. But no Afghan government will be willing to sell it. Occupying it by force would be illegal and start a new conflict in the region. To the contrary, we need regional peace in order to develop projects for connectivity and promote trade and commerce. The best solution would be paying transit fee to Afghanistan and use this land as a bridge between Central Asia and Pakistan. That would be a win-win situation for all in the long run. Now that Indians and other occupiers have been thrown out of Afghanistan, the enemies want to create hurdles in the connectivity, trade, and development in this whole region by creating new rifts, conflicts, making new proxies, and then using terrorism. Our goal should be a peaceful use of this land to facilitate trade and not to create new conflicts. The enemy wants to create multiple dimensional wedge between the regional countries and then fuel the war. We need to avoid that.
