It's not realistically possible, but here's a makeshift scenario. The Japanese do not invade French Indochina in 1940 sparking the American oil embargo. Instead of attacking the United States, Japan invades Siberia and Mongolia to help the Germans advance west of the Urals. Germany captures Moscow in 1941 and the Caucuses in 1942. Stalin is killed during the bombing of Moscow and a dispute for leadership soon takes place after that prompting a civil war within the Soviet Union. The Germans and Italians then launch a campaign to capture the Seuz canal, shortly starving Britain into surrender in 1944 and Japan conquers the rest of China by this time too. Italy captures the British colonies in the Middle East with Iraq, Syria, Palestine, and others under its control. It also invades other nations such as Iran, Arabia, Turkey, and others. Even after the defeat of the Soviet Union and Britain, this is not the end of World War II. This takes until the early 1950s to achieve though.
Germany continues to invade the remaining nations of Europe and fighting a guerrilla war with the Russians in the East. By 1950 Germany gets the atomic bomb and by 1955 gets long range bombers with the ability to reach the United States. A pro-fascist cou takes place in the rump Soviet Union and this new government becomes an ally of the Axis. Using its massive fleet of 700 long range bombers to strike at all the major US cities with atomic weaponry from bases in Siberia and western Europe. The sneak atomic attack manages to destroy a good deal of American cities including Washington D.C. with the US leadership and the President's cabinet wiped out by a weapon they didn't even know existed. America falls into a civil war scenario with weapons and aid being given from the fascist governments. Japan uses this chaos to secure control over all remaining free assets of the British and French Empire in Asia including India, Burma, Malaya, and more. The Germans allow a fleet of atomic bombers to secure the destruction of major Australian cities, now within range, but keep the secret of the bomb to themselves. An Axis invasion soon follows in succession. After this sneak attack, the Second American Civil War results in a new fascist state which uses the Monroe Doctrine to dominate the Western Hemisphere. The new fascist government of the British commonwealth also pledges to be a fascist ally of the three previous regimes by 1960 and the world is dominated by fascist governments and their allies. Any remaining resistance is simply removed by the end of the century through covert action such as cous and assassinations.
