Winston Churchill’s reaction to the 1938 Munich Agreement was to threaten war with Germany should Hitler continue his aggression.
to warn Neville Chamberlain that war was inevitable.
to declare war on Germany, thus beginning World War II.
to keep silent and let Germany handle its own affairs.

B. to warn Neville Chamberlain that war was inevitable.

Explanation:

When the Treaty of Versailles was put into effect Germany was not meant to get any of the countries they conquered after losing the war, so when Adolf Hitler sent troops to Rhineland on March 7th 1936 he went against the treaty.

So when prime minister Chamberlain told Churchill "Peace and Honor. I believe it its peace for our time"

Churchill  simply replied with the words "You were given the choice between war and dishonor. You chose dishonor and you will have war"

These words spoken by Churchill could never be more true because three years and eight days later on March 15th 1939, Germany invaded Czechoslovakia.

Then six months and fifteen days later on September 1st 1939 Germany invaded Poland, then two days after Germany invaded Poland on September 3rd 1939 Britain and France declared war on Germany.

France, Britain, Spain and Italy set themselves up for Germany to get away with not following their treaty when they allowed him to take over Rhineland. This allowed the German government and people feel that the treaty meant nothing more then writing on paper.

if the government does something the people dont like i tihnk threre would be a revolt
