Other countries, such as Germany, Austria-Hungary, Italy, and Russia all hoped to do so as well in economic advantage. Their frustrated ambitions created tensions, the limits of natural resources in many European nations began to slowly alter trade balance, and make national industries seek new territories rich in natural resources. The arms race (another cause for war) is when 1 or more parties compete to have the best armed forces. By
