The way in which international actors implement monitoring, reporting, and fact finding (MRF) mechanisms is changing. Modern MRF mechanisms date back to 1913, when, after the Balkans had erupted in war for the second time in two years, the Carnegie Endowment for International Peace initiated a commission to investigate potential violations of international law. But the Carnegie Endowment did not begin its work until fighting had ceased, believing, as the mission’s final report notes, that a mission initiated before the conflict’s conclusion would be “premature.” In contrast, almost a century later, as massive protests erupted in numerous autocratic Arab countries in 2011, international actors felt no need to hesitate. Instead, MRF actors initiated MRF missions to examine potential violations of international law in Yemen, Libya, Syria, and Bahrain, all contexts in which violent conflicts continued to unfurl, as well as Tunisia and Egypt, where massive protests had recently led to transfers of political power. These missions represent a trend in the world of MRF toward more rapid deployment.
