These expenditures include personnel salaries, equipment procurement, research and development, construction and maintenance of military facilities, and the cost of military operations around the world. For many years, US military spending has remained at a sizable percentage of its GDP. 3. U.S. military spending as a percentage of GDP Although U.S. military spending as a percentage of GDP has changed over time, it is relatively high overall.

However, in recent years, relative military spending in the United States has remained at a high level, although it has declined. 4. Comparison with other countries The United States still spends more on military expenditures as a percentage of GDP than other countries.

This gives the United States a prominent position in the global military competition. V. The impact of U.S. military spending U.S. military spending has a profound impact on its economy, its international standing, and the global security landscape.

Analyze the factors of US military spending The amount of U.S. military spending is related to its national security strategy, global status, geopolitical environment, and other factors. In addition, changes in the international situation, the emergence of new threats, and the development and application of new technologies will also affect US military spending. VII. Conclusions In general, US military spending as a percentage of GDP, although declining in recent years, remains at a high level. This reflects the importance that the United States places on its military power and its need to maintain its global position and address security challenges.
