About this Ranking
The number of neighboring countries directly impacts a nation’s security calculus. More neighbors means more potential friction points, more bilateral defense relationships to manage, and greater complexity in military planning. Countries surrounded by many neighbors often maintain larger standing armies and more diversified defense strategies.
