Established in 1971, the Dissent Channel was used 123 times in its first four decades. In modern times, about four or five dissent cables are sent each year. U.S. foreign policies that have been the subject of dissent cables have varied widely. The 1971 Blood telegram, named for its author Archer Blood, condemned the U.S. policy of support for Pakistani dictator Yahya Khan, who oversaw a genocide in East Pakistan. Other dissent cables have criticized U.S. support for various authoritarian leaders, dissented from U.S. inaction in crises and genocides, or criticized U.S. involvement in various military conflicts. For example, a 1992 dissent cable protesting the U.S. failure to act during the Bosnian genocide is credited with helping lead to the Dayton Accords. The dissent cable with the largest number of signatories, by far, was a 2017 dissent cable condemning Donald Trump's executive order imposing a travel and immigration ban on the nationals of seven majority-Muslim countries; ~1000 diplomats are listed as signatories.
