How did militarism cause tension in European nations?

Militarism heightened tensions in European nations by fostering an arms race, where countries expanded their military capabilities to outmatch one another. This competitive buildup created an environment of suspicion and fear, as nations perceived their neighbors as potential threats. Additionally, the glorification of military power and the belief in its necessity for national greatness encouraged aggressive foreign policies, further straining diplomatic relations. Ultimately, this militaristic mindset contributed to the outbreak of conflicts, including World War I.
