Like the U.S. and the other western countries, Britain wanted to stop the spread of communism.
They had alliances with countries that were involved.
Plenty of them weren't involved. In fact, any countries other than Britain and Jerusalem were basically out of the question.
The main countries involved were Germany, fighting against Britain, USA,Canada and many other smaller Allies.
The US, among other countries not involved with the European war, were spectators to the Battle of Britain, which took place in the fall of 1940. The only special effect the battle had upon the US; was the fact that Britain and the US speak a common language, and the US had at one time been part of the British Empire (Revolutionary War 1776). In effect, it was like watching our relatives involved in a fight.
Germany and Scotland, however there was a squadron of expatriate Polish pilots in Scotlands Air Force Britians are wimps though. Germany and Britain
There were 102 airfields split into 4 groups = 10, 11, 12 & 13. For a full listing and other information I suggest a visit to the Battle of Britain web @ http://www.raf.mod.uk/bob1940/11group.html
This just refers to the fact that at the time of the Battle of Britain, all other European countries had been overrun by Nazi Germany. The USA was still neutral so Britain was standing alone against a formidable enemy.
The US was a partner in an invasion that involved Britain, Canada and ten other countries.
America, Britain, Canada, France and other NATO countries facing the Soviet Union
The Royal Air Force had US, French, Canadian, New Zealand, Australian, South African, French and Polish pilots and ground crewman in its ranks throughout the Battle of Britain.
The main countries that were first in ww1 ere France, Germany, Britain, and Russia. Later on other countries, including American, joined the conflict.
