Militarism is the belief in building up strong armed forces to prepare for war. It often involves a government prioritizing military needs and spending over other areas, such as education or healthcare. Countries with militaristic policies may focus on expanding their military capabilities and influence, sometimes leading to tensions with other nations. This ideology can manifest in various ways, including increased military recruitment, the development of advanced weapons, and a culture that glorifies military service. Historical examples of militarism include the buildup of armies in Germany before World War I and the military influence in Japan during the early 20th century.
