The Three Main Effects of European Imperialism. Due to European Imperialism and many countries arguing over the land they each wanted, tensions were formed between them. Following this, many countries sought alliances between each other to feel secure. This played a big role in the outbreak of the war for many reasons.
We had the Cold War. It was called the Cold War because no military force was used in the war. It was mainly a technology race to try and scare the other country and come out superior. Espionage was also used in the war, but there was no man on man combat, and war with atomic/nuclear weapons was not conducted. I hope that answered your question, my friend.
