The foremost reason why WW2 was inevitable was the existence of three, powerful aggressor states (Germany, Italy, and Japan) with imperial and ideological ambitions that would not hesitate to use force to achieve their goals. Germany lost much of its territory and was subject to numerous military and legal restrictions as a result of the Versailles Treaty imposed on them by the victors of the First World War. Germany's leader at the time, Adolf Hitler, viewed the treaty with contempt - as a humiliation of German national pride. British Prime Minister Neville Chamberlain signed the Munich Pact with Hitler in 1938, conceding part of Czechoslovakia to Germany.
