The 1960s:

The United States continues to focus on improving its nuclear arsenal, believing it to be the key to continued world dominance. In 1963, a new enhanced radiation weapon is added to the stockpile -- the neutron bomb. This small hydrogen bomb is meant to be detonated in the air, resulting in enough radiation to kill human beings but a small enough blast to leave buildings and structures intact. During the remaining decade, 32 neutron bombs are successfully tested, though several scientists begin to question the health effects of the added fallout to the atmosphere.

This concern, coupled with the unchecked power of the United States, makes the Europeans uneasy. They propose a "nuclear club" for arsenal-holding countries. The idea is that members of the club would form a checks and balances system to openly monitor each other and share research.

In response to the idea, the U.S. stalls -- reluctant to allow other countries to restrain its place at the top of the food chain.

There continues to be no interest in space or rocket development in the United States.
