America first joined the Brits. Then, Germany attacked Russia. The Americans gave aid to the Russians to help defeat Germany. America either sent a ton of tanks to Russia or helped them build a ton of tanks. I can't remember exactly which way that worked. I think America helped Russia build tanks by improving their designs.
Britain didn't exactly ally the US. It was the other way around and the reason US got involved in the war was because Japan dropped a bomb on their Pearl Harbour. Because Japan was Axis Powered and against Britain the US allied with Britain. As well the US and Britain were already allies from before.
Two lines of thought here, first reason was Pearl Harbour, second reason was they knew they couldn't lose, as we had beaten the Germans already !
They were an ally of Japan
The Allied Forces of World War 2 consisted primarily of Britain, Russia, and the US. France was an ally as well until it fell in early 1940.
Russia
The US would have lost the only English speaking European Nation as an ally. Which would have hindered future communication with the European Continent. There would have been no major military consequences, as Britain LOST it's military prowess at the end of WW2.

Am basing my answers based on the fact that the question is on the WWII Category. Actually during war world two the US decalred war on japan in return germany declared war on the united states. Britain was always an ally of the US.
Cuba was an ally to the US during World War II. But after the war, Cuba became communist and joined on the side of Russia against US. Cuba and Russia were also launched the nuclear threat on the US and Mexico.
