Pashtunistan movement is dead.
Pashtuns are arguably the second largest demographic in Pakistan, especially in Punjab; tens of thousands are joining the Pakistani military every year. If anything, a vast majority would rather that Pashtun areas in Afghanistan be annexed by Pakistan, rather than Pashtun areas in Pakistan gain independence or go to Afghanistan.
Within a few decades, Pashtuns could very well become the largest demographic in Pakistan, which will lead to their increased political participation and importance in Pakistan, why would they give that up for a pipe dream? Why would they want to create a new nation, that will probably fall apart within a year, when they have the chance of living within a democratic nation, with huge geopolitical importance, where they will have a huge say in its future?
Despite what corrupt and irrelevant dirty bags like Mahmood Khan Achakzai and PkMAP say, Pakistani Pashtuns are patriotic. They recognize they're stronger in the Pakistani federation, rather than being independent. This is why nationalist parties are no longer popular.
