The Jamahiriya's radical direction earned the government many enemies. In February 1978, Gaddafi discovered that his head of military intelligence was plotting to kill him, and began to increasingly entrust security to his Qaddadfa tribe. Many who had seen their wealth and property confiscated turned against the administration, and a number of western-funded opposition groups were founded by exiles. Most prominent was the National Front for the Salvation of Libya (NFSL), founded in 1981 by Mohammed Magariaf, which orchestrated militant attacks against Libya's government, while another, al-Borkan, began killing Libyan diplomats abroad. Following Gaddafi's command to kill these "stray dogs", under Colonel Younis Bilgasim's leadership, the Revolutionary Committees set up overseas branches to suppress counter-revolutionary activity, assassinating various dissidents. Although nearby nations like Syria also used hit squads, Gaddafi was unusual in publicly bragging about his administration's use of them; in June 1980, he ordered all dissidents to return home or be "liquidated wherever you are."
