This report by the RAND corporation explores the impact of export controls related to drones on US political, economical, and security interests. Particularly the Missile Technology Control Regime is being considered, and the authors conclude that even though the MTCR had some success in limiting the proliferation of large drones, the rise of non-MTCR members and the production of drones just below the MTCR category limit have both contributed to the erosion of the MTCR’s efficacy.
