International relations significantly influence national security policies by shaping a country’s strategic priorities and defense strategies. Factors such as alliances, conflicts, and global power dynamics dictate how nations assess potential threats and opportunities. Diplomatic engagements or tensions with other states often lead to adjustments in defense budgets and military positioning. In an interconnected world, countries must consider not only bilateral relationships but also multilateral agreements and global challenges, such as terrorism and climate change. Ultimately, the interplay between international relations and national security policies shapes a nation’s overall security framework.
