Hello there
I am the surfer
The british fought alone the battle of britain
they did most of the fighting for Malta
They had good military industry of their own : tanks, submarines, air planes.....guns and more
They fought for Africa
They got valuable help from Canada, New Zealand, India, Australia and South Africa
They got a good navy with air craft carriers
They did the naval attack on Tarento
They decipher german radio codes
The soviets did most of fighting 8/10 german soldiers were killed by red army, no british city was under siege like Leningrad, no terrible battles like Stalingrad....
The germans produced 8,000 stukas, the soviets 30,000 il 2 tank buster for similar dive bomber role!
The soviets had the best allied tank of those hard times!
With out the usa england , british commonwealth and soviet union would defeat germany by themselves , war would take 2 , 3 or more years but in the end germany was surrounded and attacked by west and east by determined enemies who fought until the end!
Internal consequences if usa did not join the war
The entry into the war meant gearing up for mass production and money spending creating jobs
1.) No federal spending on military budget means no increase of production so no factory jobs for those with out jobs so the continuation of poverty
2.) No stock market share for war bonds!
3.) No increase of military production meant us armed forces were ill prepared for foreign war, us military capacity before 41 was like that of Yugoslavia
Canadian navy was little before war, after that the canadian navy became the 3rd world´s largest!
4.) No mayor technological development means no jeep, no great airplanes, no expansion of industrial base to produce the dc 3 and so on!
5.) The car industry got benefits of expansion cause of military contracts so in the absence of war no mayor car production
6) Intelligence gathering capacity. OSS was funded to gather intel on the enemy with out war there would not be post war CIA or NSA......
Consequences for the world after 45
After the war usa become big brother of freedom so with out us the soviets could have won the cold war, europe and british commonwealth were little to oppose soviet expansion
No marshall plan to help Europe to recover from war disaster
The soviets tried to take over Berlin, to remove western presence, so no Berlin Airlift.
The Chinese and north korea attacked south korea and the usa lead the defense of little south korea because usa was big brother so with out big brother south korea and the whole of asia would become red back yard!
No cuban crises, soviets would have no reason to install missiles to oppose a neutral usa.....
No space race
No nasa, german rockets were the start point to reach the moon , so who would take nazi rockets to launch vehicles and men to the moon!? most likely the soviets! but certainly not so the usa!
No vietnam war!
European support for Israel, if america remained neutral , years later the americans and the israelis would not became close friends the way they had or would do so under another scenario!
