Toothache

Britain is this week celebrating the Battle of Britain, which took place 70 years ago.
Professor A.J.P. Taylor, in his Origins of the Second World War, argues that Hitler had no territorial ambitions in Western Europe; he admired Britain; and he wanted to achieve his aims in the East with the threat of war and/or with mini wars.
Britain declared war on Germany (3 September 1939) because Germany attacked Poland. But it begs the question: Why didn't Britain then declare war on the Soviet Union when she also attacked Poland a few days later?
The "miracle of Dunkirk", when 300,000 British soldiers escaped across the Channel, was not due to a blunder by Hitler. He ordered his tank commanders to stop because he wanted to make peace with Britain and France.
Britain's Foreign Secretary, Halifax, wanted to make peace, and with Prime Minister Chamberlain's resignation in May 1940 the choice of Prime Minister lay between him and Churchill. Unfortunately, Halifax had toothache!
What were the Germans supposed to do, with a country that would not make peace? (They weren't requiring Britain's surrender.)
As for the "blitz", the Luftwaffe was destroying the Royal Air Force on the ground, so Churchill ordered some bombers to bomb Berlin. Hitler took the bait, and changed targets from airfields to cities. The Luftwaffe was not pleased.
In 1945 Goering, head of the Luftwaffe, told his British captors that Germany hadn't wanted war with Britain; that though the British thought they had won a great victory they would lose their Empire.
When Britain's colonies became independent they promptly imposed travel restrictions on the British; Britain did not bring in the Commonwealth Immigrants Act until the end of June 1962.
If there are no travel restrictions the question of Marriage and Migration does not arise.
Therefore, as far as Britain and the Commonwealth is concerned, people use marriage to occupy the UK - because of a toothache!
