It was rather we who included the west Pakistanis. So, do not twist and ask your PM about the truth. He knows the true answer.Two nation theory didn't fail. Muslims are indeed a separate nation. The mistake the theory made was thinking it was a good idea to include bangladesh in the Muslim nation. They clearly identify with their race first and faith last.
Your kind of people in west Pakistan are responsible for the 1971 war and the consequent bifurcation of Pakistan.
