Was Hitler Primarily Responsible for the Outbreak of the Second World War

Hitler was primarily responsible for the outbreak of the Second World War. He was too ambitious that he constantly violated the Treaty of Versailles to rearm and invade other countries, and even ignored the ultimatum sent by Britain and invaded Poland which directly marked the beginning of the Second World War.

Firstly, his adoption of expansionist policy posed a serious threat to world peace. Germany built up a strong army, which made a war more and more possible at the time, with large amount of population and resources plumped into military, alarming the other countries to rearm.

In 1938, he demanded Sudetenland and succeeded in getting the land in the Munich Agreement, while Hitler promised that it would be the last land he wanted to get. He ate his own words just one year later, annexing the whole Czechoslovakia in 1939, showing that he had no intention to keep his promise and cooperate with other countries. By that time, Britain had sent an ultimatum to Germany saying that ‘Withdraw, or we are at war’. Yet, Hitler ignored the ultimatum and invaded Poland after signing the Nazi-Soviet Non-Aggression Pact...
