"Rogue state" is a term applied by some international theorists to states that they consider threatening to the world's peace. These states meet certain criteria, such as being ruled by authoritarian or totalitarian governments that severely restrict human rights, sponsoring terrorism, or seeking to proliferate weapons of mass destruction. The term is used most by the United States ; in his speech at the United Nations (UN) in 2017, U.S. President Donald Trump reiterated this phrase. U.S. politicians have used the term to describe countries such as Iran, Syria, North Korea, Afghanistan, Cuba and Venezuela. However, the term has been applied to other countries, as well as to the United States itself.
