Why was the battle of Britain controversial?

Answer 1

In the Battle of Britain, the Empire stood up, alone, against the might of Nazi Germany after it had demolished Poland, Holland, Denmark, Belgium, France, and Norway. Churchill said, "Even if the Empire should last for a thousand years, men will look back on this and say, 'This was their Finest Hour.'" Some critics thought he should have sued for peace, instead.

Answer 2

The Battle of Britian was used as an example as to why Canada should be trying to save the free world, namely the UK, from the Nazi's. Those who did not agree that we should be rushing off to get involved in saving the world, particularly a British world, did not appreciate the obvious political ploy.

At the time of the Battle of Britain major countries, most notably the United States, were standing by and not getting involved. Canada and other members of the commonwealth were the only thing standing between the Nazis and the world. Controversial, even to this day, for obvious reasons. People do not want to be reminded that they had picked the wrong side to support.
