The Missile Technology Control Regime (MTCR) is an attempt to control the proliferation of missile technology. However, knockoffs of Russian Scuds are everywhere, China keeps getting caught selling missiles and parts to various countries in spite of repeated promises, and North Korea, Syria and Iran freely exchange missile equipment and expertise. Iran has been using front companies to secretly shop for missile parts that enable it to reach Europe. Similarly, North Korea keeps testing missiles that can reach the U.S., albeit with poor accuracy. Meanwhile, the Trump administration alleged Russian violations of the Intermediate-Range Nuclear Forces Treaty (INF) on medium-range missiles and withdrew from the treaty.
