The two nation theory, championed by the Muslim League, led to the partition of India and the creation of Pakistan in 1947. But the two wings of Pakistan, called West Pakistan and East Pakistan separated by 1600 kms of Indian territory, could not live in harmony despite religious homogeneity. Their ethnic, linguistic, economic and cultural diversities could not be bridged by an emotional appeal to religion. Consequently, fissures started erupting in the politics of Pakistan soon after the Independence and with each passing year these widened. The Indo-Pak War of 1965 also contributed to this growing divide. Bereft of appropriate defence infrastructure, East Pakistan felt isolated and abandoned. Finally, the malfeasance of Pakistani leadership, after the 1970 elections, proved the proverbial last straw on the camel's back.
