Czechoslovakia had a modern, well-prepared military and Hitler, on entering Prague, conceded that a war would have cost Germany much blood. But the decision by France and Great Britain not to defend Czechoslovakia in the event of war (and the exclusion from the equation of the Soviet Union, whom Chamberlain distrusted) meant that the outcome would have been uncertain. This event forms the main part of what became known as Munich betrayal (Czech: "Mnichovská zrada") in Czechoslovakia and the rest of Eastern Europe, as the Czech view was that Britain and France pressured them to cede territory in order to prevent a major war that would involve the West. The Western view is that they were pressured in order to save Czechoslovakia from total annihilation.
