We don't really give two shits about Afghanistan. We are mostly ignoring their snarky comments, building border walls, trenches and fortifications and overall distancing ourselves from them.
Since 1947, engaging with these people have brought us nothing but negative consequences. Pakistan has always wanted friendly relations with them and we have tried everything. We supported them the most during the Afghan war, we hosted millions and millions of Afghan refugees, we have ceded land to them, we have provided thousands of scholarships, admitted hundreds of Afghan cadet, given much aid and so much more.
They on the other hand have harbored and supported rebel leaders, support separatism in KPK, stood against us in the international stage, supported leftist terrorist groups, initiated many skirmishes, launch incursions, mobilize armies on the border (during wars with India), gave a blind eye to Afghan terrorists entering Pakistan and so much more.
How can you even deal with a people like them. They don't recognize the border, claim that Pakistani militants are crossing the border into Afghanistan and complain (have even attacked at times) whenever we build fortifications, posts and fences on the border.
Truth is, Afghanistan will remain a shithole; no matter how many times Ghani takes a picture with daddy Trump. Pakistan has a bright future, I have seen it; I am optimistic about the future and happy where we are going. Afghans will always remain on the sidelines, barking out of envy and hate to distract themselves from the reality and their burning country.
