The book is really concerned with the inter-linked future of India and Pakistan, and the various facets of the Muslim Problem, geo-political, pan-Islamic and all that. It tears apart Jinnah's Two-Nation Theory, analyses the working of the Islamic State of Pakistan, appraises its chances of survival.
However, the survival of Pakistan is not the question, nor its viability. Pakistan can live and prosper as an independent, sovereign, modern state like Switzerland. Alternatively it may settle down as an autonomous region in a larger confederal polity covering the whole subcontinent. Presently, Pakistan is in a state of uneasy equilibrium, the powers that be having opted for an Islamic State.
The author has therefore devoted a substantial part of the book to proving how making religion the basis of the State in Pakistan is destroying the State itself!
