Imagine what the Cold War would be like if instead of Canada and Mexico the U.S. had the Soviet Union to the north and the People's Republic of China to the south. That is the geopolitical reality of the Indian subcontinent. Sharing India's Western border is Pakistan - plenty of bad blood flows between the two nations after a tumultuous separation of the two in 1947 and a number of wars since, the most recent armed conflict occurring just 15 years ago. If Pakistan is India's Soviet Union, then there's no question who would be their China - quite simply and literally, it's China. Sharing India's Eastern border, the PRC is a major strategic competitor to India by geographical default and control of the Indian Ocean and the South-East Pacific by one nation puts the other in a submissive bind (as well as many other nations, including Singapore, Taiwan, Vietnam, the Philippines, Indonesia and Japan). This has made Pakistan and China natural allies-of-convenience, and whatever chunk of Pakistan's war machine that isn't directly supplied by the U.S. is directly supplied by the PRC - constituting a very, very large chunk. With the PRC fielding stealth prototype and pre-production fighters, and a high likelihood of Pakistan benefiting with at least improved 4/4+ Generation fighters, it's a foregone conclusion that India would attempt development of stealth fighters of their own. But they can't wait for the years if not decades of development needed to counter their adversaries' efforts, not with China's examples already airborne and just waiting for full production. The Indians are going for a three-tier approach: acquire/co-develop what they can get from the West, acquire/co-develop what they can get from Russia, and in the meantime their own aerospace engineers can keep busy on a true and fully-indigenous Indian stealth fighter.
