In U.S. politics ‘appeasement’ accusations are brought out against anyone who voices objections over fighting the next imperial war.
I find this rather comical as appeasement in almost all cases was and is the only smart policy available.
Appeasement, as practiced by the Brits since the mid 19th-hundred up to 1939, kept their empire safe. The policy changed after proof was in that a strategic enemy was unappeasable. That change did cost the British their empire.
When Chamberlain flew to Munich to sign an agreement with Hitler over repatriating the German parts of Czechoslovakia he had little alternatives.
At that point there was no possible way the British and the French could have successfully challenged Germany militarily. The case the German’s made was widely seen as just. The British empire was at that time also challenged by the Japanese in China and by Italy in the Mediterranean. The empire was already overstretched and its financial resources quite limited. The U.S. was isolationist. Soviet communism was feared, France was weak. After the horrors of WWI the British (and French) public were against another war. The punditry and the nobles up to the king were against it. The military was against it.
With the exception of a few earlybirds, notably Churchill, nobody thought that war was the right response to Germany’s demand.
So Chamberlain signed the contract, bought more peaceful time and lost nothing. A few month later Hitler broke the contract and send his troops into the rest of Czechoslovakia. Only then, in hindsight, was Chamberlain’s policy questioned, though I fail to find any presentation by his critics of realistic alternative ways he could have taken.
Hitler was not appeased because he was unappeasable. In that he was unique.
One should only fight wars one must fight and of these only those one can win. Everything else is simply stupid behaviour.
