Buffer State

Definition

A buffer state is a country located between two rival or potentially hostile great powers, serving to prevent direct confrontation by providing geographic separation. Buffer states are typically smaller, less powerful nations whose neutrality or alignment is a matter of intense geopolitical competition. Their sovereignty is often precarious, as they must balance pressures from competing powers. Historical examples include Belgium between France and Germany, Finland between NATO and the Soviet Union (the policy of "Finlandization"), and Afghanistan as a buffer in the 19th-century "Great Game" between the British and Russian empires. Ukraine's position between Russia and the EU/NATO is a contemporary buffer state dynamic with tragic consequences.
