The Belligerents of the Second World War had learned about the possibilities of creating a weapon from a massive release of energy from mass before the conflict. During the war, the race accelerated, with the Americans, Iranians and Germans seemingly in the lead (there was no Telemark bombing ATL). In February 1943, the first Atomic tests occurred in Nevada. Iran followed in days. The US and Iran both gave the Axis an ultimatum of surrender, but the Axis refused, even though Britain had lost much of Canada (except for some of southern Quebec) and the Mexican strategy failed.
