In recent years the JDF has been called on to assist the nation's police, the Jamaica Constabulary Force (JCF), in fighting drug smuggling and a rising crime rate which includes one of the highest murder rates in the world. JDF units actively conduct armed patrols with the JCF in high-crime areas and known gang neighbourhoods. There has been vocal controversy as well as support of this JDF role. In early 2005, an Opposition leader, Edward Seaga, called for the merger of the JDF and JCF. This has not garnered support in either organisation nor among the majority of citizens. In 2017, Jamaica signed the UN treaty on the Prohibition of Nuclear Weapons.
