myths , lies only.
firstly russia didnt invade afghanistan but was invited with desperate pleas by then communist govt there, it has no plans for invasion of afghanistan and it was purely an stabilizing move in first years.
well what would have happened if russia had stabilized afghanistan?
ressurgence of communist inspired movements specially in those times remember we were in worst dictatorship.
violence or small scale insurgencies in balochistan and in sindh so either way problems would have been there but those could not have arisen should we had democratic/popular setup.
