After the U.S. accused Libya of orchestrating the 1986 Berlin discotheque bombing, in which two American soldiers died, Reagan decided to retaliate militarily. The Central Intelligence Agency were critical of the move, believing that Syria were a greater threat and that an attack would strengthen Gaddafi's reputation; however Libya was recognised as a "soft target." Reagan was supported by the U.K. but opposed by other European allies, who argued that it would contravene international law. In Operation El Dorado Canyon, orchestrated on 15 April 1986, U.S. military planes launched a series of air-strikes on Libya, bombing military installations in various parts of the country, killing around 100 Libyans, including several civilians. One of the targets had been Gaddafi's home. Himself unharmed, two of Gaddafi's sons were injured, and he claimed that his four-year-old adopted daughter Hanna was killed, although her existence has since been questioned.  In the immediate aftermath, Gaddafi retreated to the desert to meditate, while there were sporadic clashes between Gaddafists and army officers who wanted to overthrow the government. Although the U.S. was condemned internationally, Reagan received a popularity boost at home. Publicly lambasting U.S. imperialism, Gaddafi's reputation as an anti-imperialist was strengthened both domestically and across the Arab world, and in June 1986, he ordered the names of the month to be changed in Libya.
