Defense spending refers to the financial resources allocated by a government to maintain and enhance its military capabilities. This includes funding for personnel, equipment, training, and operations. Countries often prioritize defense spending to ensure national security and respond to potential threats. Governments typically determine their defense budgets based on various factors, including geopolitical situations, economic conditions, and strategic goals. For example, the United States has one of the highest defense budgets globally, reflecting its role in international security and military presence around the world.
