From the Introduction: "In March 2018, the United States submitted a proposal to the Missile Technology Control Regime (MTCR) partners that would relax the regime's export guidelines for certain Unmanned Aerial Systems (UAS). Advocates of altering the guidelines to ease such exports argue that increasing competition from foreign UAS manufacturers is undermining the competitive advantage of their U.S. counterparts. Other observers have emphasized the need to maintain the MTCR's standards, which are widely regarded as effective."
