I am not sure if this is what you are looking for but the way Britain and France gave in to Hitler's demands was called Appeasement.
Unconditional Surrender
The end of the war between Britain and France.
If you are asking about World War II, Britain and France had a defence agreement with Poland which stated that if Poland was attacked, Britain and France would come to its aid. On September 1st 1939, German troops invaded Poland. Britain and France demanded that Germany should immediately withdraw its troops from Poland. The German government ignored the demand so on September 3rd 1939, Britain and France simultaneously declared war on Germany.
They did not ultimately give into Hitler's demands they came to an agreement with him that would meet them.
That's a strange interpretation of history! In the late 1930's, Britain and France had a defence agreement with Poland which stated that if Poland was attacked by another country, Britain and France would come to its aid. On September 1st 1939, German troops invaded Poland without warning. Britain and France then issued an ultimatum to Germany saying that if they did not immediately withdraw their troops from Poland, 'a state of war would exist'. Germany totally ignored the demand to withdraw, so on September 3rd 1939, Britain and France jointly declared war on Germany.
German troops attacked Poland on Septemer 1st 1939. Britain and France declared war on Germany two days later. But also before that, Germany had been taking and bringing other countries into the Third Reich. France was conquered in as little as 6 weeks which showed how well Germany's army was built.
According to some, appeasement was reasonable because Great Britain and France were in no shape to fight another war with Germany. The only other option was appeasement, which allowed Germany to take control of the Sudetenland. Some say that it encouraged Germany to demand even more, but to most officials in France and Great Britain, appeasement was the most reasonable solution.
The United States and Great Britain argued over who should be Oregon. President Polk asked his people to demand that the US have it. Basically Polk bluffed Great Britain into giving most of Oregon to the United States.
I'm not sure, they wanted Germany to restrict it's territorial demands. Chamberlain returned to Britain hailing 'Peace in our time'. On a scale of 1 to 10 in being wrong it scores 11.
The demand for independence from France is strongest in the French overseas territory of New Caledonia, located in the Pacific Ocean. The indigenous Kanak people have been advocating for independence and have held referendums on the issue.
