1945-1955 The Divided World After the Secomd Great War, the world began to gravitate into several camps. The first camp was the facist nations of Europe. These nations, led by Hitler, in Germany, consisted of Germany, Spain, Italy, Norway, Sweden, France, and a somewhat emaciated Russia. The second camp consisted of the democratic and socialist nations of the globe. These included the United States, Britain, Canada, India, and much of Latin America. The third camp consisted of the non-aligned nations. Foremost among them was Japan, and the East Asia Co-Prosperity Sphere over which it presided. The sphere was wracked by bloody civil war, especially on the Chinese mainland. By 1950, nuclear weapons had been stockpiled by Germany, England, the United States, and Japan.
The democratic-socialist nations and the facist nations of the world enjoyed an uneasy ceasefire. However, in the early fifties Germany began stepping up efforts to secure it's future. They moved decisively to oust the goverments of Turkey, Kurdistan, Iraq, and Kuwait and replace them with more agreeable despots who could preserve Europe's oil supply. German and Italian troops even invaded Libya. These actions incensed the remainder of the globe. In the Americas and Africa the United States and England pursued a similar, if more covert, program of encouraging pro-Washington governments.
1948-1951 Sunset for the Kingfish Huey Long barely manged to scrape into his thrid term in office. However, one reelected he took steps to, he thought, secure National Patriotic Party authority. He admitted five new states to the union. They included Hawaii, Alaska, Puerto Rico, the Phillipines, and Mindanao (the S. Phillipines). The economy continued to improve and many Americans began to see the US as a land of plenty once again. America began to strengthen it's place as an opponent of facism worldwide, and finished the construction of it's nuclear arsenal. In 1951, while walking to his limousine one morning Huey Long was shot dead by Ralph Shelley, a man ruined by Long's corrupt policies. After his death, he was said to be the most influential man in America that century.

By an Axis invasion of Libya did you mean the suppression of an independence movement there? It was an Italian colony before the war and given they were on the winning side I doubt that would have changed much.
Where the Germans/Italians might be having problems is with the Arabs by this time. Given the nature of anti-Semitism and the desire for more resources there, especially as oil becomes more and more important, I can see they facing a grim future in a Nazi controlled world.
To refer back to a couple of earlier bits as I've been busy and unable to reply much recently. I can't see either side getting nukes by 45 without the US's industrial resources, not unless Britain got very lucky. Suspect we would get it before Germany, with the mess they made of their physics and the flow of émigré scientists and desperation of the democracies. However doubt if it would be before late 46, more probably 47 as a guesstimate.
If Germany did get the bomb 1st, although they might struggle to deliver it to somewhere as central as Birmingham, I can't see Britain maintaining any independence. Especially not after fighting so long and bitterly against Hitler. If somehow we did I think it would be unlikely Long would commit himself to an alliance with Britain.
I also doubt that Japan, with all its problems holding down such a massive empire, would get the bomb by 1950.
However interesting scenario and frighteningly possible under the circumstances.
