International relations significantly shape national military policies as countries respond to global security challenges and alliances. Foreign threats or conflicts may prompt nations to enhance their military capabilities, invest in defense technology, or establish strategic partnerships. Geopolitical considerations drive decisions regarding military funding, troop deployment, and participation in multinational operations. Additionally, shifts in global power dynamics necessitate adaptations in military strategy, as countries reassess their roles on the world stage. Ultimately, international relations influence national defense priorities, prompting a balance between deterrence and diplomacy in military policymaking.
