Robert Clive successfully shoots himself. The French dominate India, while Britain moves closer to Prussia, eventually forming 'the Union', which keeps some of its American colonies but remains a second rank power behind France. Other nations of notice include the Northern System (Russia and its allies), Sweden (the first nation to gain the atomic bomb in TTL's late 20th century), the Dutch Empire, Zululand (a very technologically advanced nation), the Ottoman Socialist Ummah, and two Jewish states (one in Texas and the other on Madagascar). Cliveless World includes the development of the ideology of Panopticonism, which is essentially a much earlier development of the surveillance society. In addition, medical and agricultural science is in advance of OTL and the world population is 10 billion by 2000.
