In my thesis I am writing about why and how Great Britain is partly responsible for the outbreak of World War I. The British statesmen failed to recognize the unique situation of Germany and Austria-Hungary that influenced these nations to go to war. Britain should have understood their situation better. Britain’s attitude towards the Entente Cordiale and its members was one sided. This linked up with the policy of appeasement and détente with Germany led to a fragile and uncertain international situation, which cannot be disregarded when studying the causes of the outbreak of the Great War.
