How was Britain defended in the World War 2?

Answer 1

Actually Germany declined to invade Great Britain as Hitler was much more into invading Russia (big mistake #1). Great Britain however did put a lot of effort into fortifying its coast-line, had the world's best navy and the RAF worked over-time fighting against the constant bombing. Canadian forces were stationed in England as a home guard until the D-day invasion of Europe.You could say everyone involved were defeat by ww2, economy wise, everyone lost so much money, hence the great depression.

Answer 2

After the fall of France in June 1940 it was obvious that Britain was next on the list of Hitlers conquests. The threat was very real. But the Royal Navy was huge at the time, to cross the English Channel Hitlers forces must secure air superiority, at the very least over the invasion beaches & the immediate bridgehead area. Churchill was very worried about the French fleet being absorbed by the German Navy. When Goerings' Luftwaffe were unable to win the Battle of Britain & turned to bombing British cities, largely at night, it became a much less potent threat. The threat was removed entirely in the summer of 1941 when Hitler moved east against Russia. The simple fact remains that Hitlers land forces were very, very powerful, but transporting them across the channel was an obstacle they had not the means to undertake: Had they landed in significant numbers in England in the autumn of 1940 then it is highly possible that London might have been occupied within, say, 2 weeks (Ok, I am being hypothetical here) but where the naval forces might have come from at the time is another question.
