Here are some of the problems militarism caused:
1) Increased tensions between European powers: The arms race and military buildup between European countries led to increased suspicion and mistrust. Each country was suspicious of its neighbors' intentions and feared being attacked. This climate of fear and suspicion made it difficult to resolve diplomatic conflicts peacefully.
2) Diverted resources from other areas: Governments poured vast sums of money into building up their militaries. This money was diverted from other important areas such as education, healthcare, and infrastructure. As a result, European economies suffered and the quality of life for citizens declined.
3) Promoted a culture of violence: The glorification of the military and the cult of heroism associated with war created a society in which violence was seen as a legitimate and even desirable way to resolve conflicts. This culture of violence contributed to the ease with which World War I began and the brutality with which it was fought.
4) Undermined the balance of power: The rapid buildup of arms by Germany, France, Russia, and Great Britain led to an arms race that spiraled out of control. As a result, the balance of power in Europe was undermined and it became more difficult to maintain peace.
5) Contributed to the outbreak of World War I: The arms race, military buildup, and culture of violence in Europe all contributed to the outbreak of World War I. The war was a direct result of militarism and the failure of diplomacy.
