Buffer zones: Anachronism, power vacuum, or confidence builder?

Abstract

AbstractAmidst calls for containing an assertive Russia, politicians and pundits have been debating whether Ukraine should serve as a ‘buffer zone’ between the Russian and Western spheres of influence. These debates provide an opportunity to revisit the long and varied history of major powers’ efforts to manage buffer zones. We draw on this history to learn the conditions under which buffer zones succeed or fail to stabilise regions, how buffers are most successfully managed, and when alternative arrangements for borderlands work better.
