While I agree that America profited during the War early on, YOU did not save Europe the second time. You got your ass handed to you at Dunkirk and but for the stupidity of the Germans, should have been annihilated then and there. Hitler also made terrible blunders during the battle of britain.
That the enemy blunders in war doesn't detract from the success of the victor. It shows that the enemy erred yet we didn't.
I agree we underestimated the Nazis during the 'phoney war'.
But to suggest that Britain was 'saved' detracts from the truth. Britain had already 'saved' itself, and the free world, before America joined the war. The turning point was the Battle of Britain.
Let's put a little supposition together. Suppose the pilots of the RAF hadn't fought like lions and won. Imagine if the Nazis had knocked out the RAF, and crossed the channel. With the Royal Navy at the time the largest in the world, and with a good proportion of it in home dock, the Nazis would have captured this.
America would then be facing capable enemies on two sides, the Japanese on the Pacific coast, the Nazis on the Atlantic. Not a pretty picture. America would have been forced into a peace with Nazi Germany, to enable it to fight the Japanese.
In the meantime, the world's Jews, Gypsies, Socialists and homosexuals would have been exterminated, and the Nazi's would have been able to concentrate on defeating Russia.
But that didn't happen. The RAF prevented this.
Without the US in the war, something that FDR wanted much earlier but silly ass isolationists in this country objected to, you could not have done more than MAYBE kept the Island free of Germans.
Another American myth concerning WWII.
After the success in the Battle of Britain in October 1940 and before the Americans finally joined the war in December 1941 Britain might not have launched an invasion of mainland Europe, but we did take the war to the Nazis and the Axis powers across the globe. On land, in North and Central Africa, Norway and the Middle East, in the air over Europe and on the seas everywhere. To suggest that Britain was finished after the minor setback of the inevitable collapse of France and Dunkirk shows a deep underestimation of Britain as a fighting nation.
Our industrial might and population base used to fight a war was the prime reason Germany lost.
That is overselling your part in the German war. The setback that was the Battle of Britain forced Hitler to turn east too late in the year to reach Moscow before winter set in. The Soviets then mauled the German Army. Whilst American reinforcements expedited the reconquest of Europe, the battles that turned the tide against the Nazis were not American but British and Russian.
While I admire the brits, especially their almost devout alliance with the US, you oversell your position.
Pot, meet kettle.
As for our devoutness, we have in the last half century, had shockingly weak leaders. Including Thatcher. That will change.
As to "giving away the empire voluntarily" I think the Indian's might object to your overly altruistic view of how you gave up your empire, and I KNOW the Irish would.
I am sure that if we had been not been financially diasabled by two world wars, we would have been able to install reforms in India as a response to the uprisings and have crushed any violent rebellion. We succeeded in this in 1857. And as for Ireland, the internal issues of the British Isles is complex. Migration between Ireland, Scotland, England and Wales over the milenia makes the Irish issue more civil war than Empire.
Many factors contributed to the end of the British Empire. The same liberal movements which saw the British Empire end slavery and the slave trade from 1807 and also missionary expeditions into Africa built to an extent that the upper middle classes, which provided most of the officer corps and Imperial Civil Service lost the taste for empire. After fighting two world wars to prevent tyrannical Germanic conquests of Europe, Britain was also broke, emphasised by the extortion of the US towards war-supplies during World War II.
The British Empire didn't end in military ignomy like the Western Roman Empire, or swept away by a new religious empire like the Byzantine Empire. The British Empire simply retired undefeated.
