As nations on both sides wanted to conquer more territories and build up colonies, those that were attacked were usually a 3rd world country and were already allied to the Allies or vice versa. This also helped spark the war for ww1, even tho the main reason was the assissination of Archduke of Austria-Hungary.
For ww2, many Axis nations didnt like the turn out of the Treaty of Versailles. Germany, becuase they had to pay a huge sum of money to the Allies, and literally became bankrupt.
Japan, for they did not get all the lands they wanted, and their European and American allies didnt want to hear them out.
Italy, because they also didnt get anything that they were hoping for.
During WW2, many nations called upon their colonies to help them fight the war. Some examples would be India and Britain, Egypt and Britain, etc etc.
World War 1 started Jul 28, 1914 and ended Nov 11, 1918.
German planning<span>, beginning in 1896, was predicated on the numerical inferiority of the German Navy versus that of the British and sought the same goal of decisive battle. By 1905 German strategy rested on a defense of their major ports against a close blockade through placing the battle fleet in the region of Heligoland Bight and in the principle naval bases of the North Sea.
During 1915-1917, the Germans made U-boats to strengthen their naval power which they thought would lead to their victory in the war. </span>I hope my answer has come to your help. Thank you for posting your question here in Brainly.
