The Muslim League's demand for the creation of Pakistan was rejected by the Simon Commission as it was not viable. The creation of Pakistan would not solve the communal problem and the Cabinet Mission found no reason to merge the non-Muslim parts of Bengal, Punjab, and Assam. It would also result in disruption of the Indian armed forces, telegraph lines, and the postal system, foster logistical problems in creating Pakistan and put the princely states in a dilemma whether to join India or Pakistan.
