Foreign Internal Defense

Foreign internal defense (FID) is a term used by a number of Western militaries, including the United States, France and the United Kingdom, to describe an approach to combating actual or threatened insurgency in a foreign state called the Host Nation (HN). The term counter-insurgency is more commonly used worldwide than FID. FID involves military deployment of counter-insurgency specialists. According to the US doctrinal manual, Joint Publication 3-07.1: Foreign Internal Defense (FID), those specialists preferably do not themselves fight the insurgents. Doctrine calls for a close working relationship between the HN government and military with outside military, diplomatic, economic, and other specialists. The most successful FID actions prevent actual violence, although that is rarely possible. When combat is needed, it is best done by HN personnel with appropriate external support, the external support preferably being in a noncombat support and training role alone.

Famous quotes containing the words foreign, internal and/or defense:

    “The condition every art requires is, not so much freedom from restriction, as freedom from adulteration and from the intrusion of foreign matter.”
    —Willa Cather (1876–1947)

    “If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
    —Leon Trotsky (1879–1940)

    “The aims of life are the best defense against death.”
    —Primo Levi (1919–1987)
