@tamsen_ikard your claims of afghanistan hating pakistan merre existence is inflammatory lie that tries to demonize afghanistan, that small campaign lasted only 1 year, that's very short campaign from a country that hate their "mere existence" as you said.
Pakistan is not the US or even a big western country that can invade another country while having the backing of the west, and pakistan will not have backing from russia or india or other ASEAN countries, and they'll be lucky if China gave them some backing.
Your "conquering" will just lead to pakistan been threatend & blackmailed by the west to implement their policies, like gender equality and changes to the education system, which will lead to rallies from afghans and they'll see pakistan as a US's proxy -- > therefore more uprisings, more operations even inside of pakistan,...etc.
And Pakistan will have to manage a country that was torn out by the Soviet & US occupation, and every failure will be Pakistan's fault.
India and countries that have enemosity against pakistan, like Israel, will have the biggest laugh out of this "idea" of yours.
You don't know what you talk about, so stop your warmongering and inflammatory posts.
