Even though the writers behind Ayn Rand Institute and Ayn Rand Lexicon define themselves as Objectivists and are more often opposed to libertarians, large minorities of right-libertarians, mainly in the United states, use aspects of Ayn Rand's Objectivism to justify their foreign policy beliefs on the right of defense. A very common view on dictatorship among these is the view that a dictatorial society is an outlaw that can claim no rights and that any free society has a right to forcibly change any dictatorial society into another free one, but should absolutely not assume this to be any kind of self-sacrificial duty. When it comes to broader American foreign policy, these libertarians believe that the crux of American foreign policy should be free trade, including abolition of protectionism as a corporatist element. Many libertarians will argue from perspectives most associated with Ayn Rand Institute to justify siding with Israel over the Arab League, regarding the war that the Arab League launched against Israel in 1948. Some libertarians will use Objectivist arguments to criticize the tendency of many of their own to focus on trivial crimes by free societies instead of severe crimes by tyrannical societies.
