Welcome to the Diplomatic Capacity Index
For years, diplomats and students of diplomacy have raised concerns about a crisis in diplomacy. But it is only recently that this issue has found its way into more mainstream conversations about diplomacy as an instrument of national capabilities and the peaceful resolution of international issues. Although there is a growing sense that waning diplomatic resources may reduce the ability of a state to effectively pursue its interests, there is little systematic data available to assess the diplomatic capabilities of states.
FPI is giving fresh attention to a project that we hope will help provide at least one such data set. We have produced a test "Diplomatic Capacity Index," an index that will look comparatively across countries to measure relative commitments by countries to diplomatic capabilities. What we measure and compare will depend upon how we define and operationalize diplomacy.
Below you will find a number of resources related to our project.
