Lets see! Spain joins Hitler in war and is crushed by the American led forces. Sometime in 1943, the US decides to invade the Balkans rather than Italy and has a strong foothold there by the time the Soviets break out, and drive further west into Germany.
The post war Europe map is drawn differently, Italy votes to go Socialist but does not go communist, probably part of the non-aligned movement, eventually anyway. Maybe even have a post-war provision added to their constitution forbidding them from making alliances.
Maybe Hitler declares war on Turkey or there is some sort of communist revolution? Not quite sure of this one.
Israel never comes about or is destroyed during the Suez Canal War and there is a union with Syria, Jordan, Palestine, and Egypt, maybe Jerusalem is the capital of this Arabian Union?
Britain and France get angry at the United States for not supporting them in the Suez Canal War and NATO Breaks apart. There is some bad blood between the UK and US, with the US showing support for Ireland in the troubles there, and Rhodesia when they secede from Britain. The Commonwealth forms an alliance sort of like NATO.
Charles de Gualle does not want to be a British or American "puppet" so he starts France off on its own course forming yet another power bloc.
The Soviets get northeastern Europe as their allies, the US gets southeastern Europe and Spain, as well as a good part of Latin America.
