¹ Perhaps the most famous is that of Justice Washington in Bas v. Tingy, 4 Dallas 37, referred to in Warren, Charles, The Supreme Court in United States History, Vol. 1, at 156:Google Scholar “It may, I believe, be safely laid down, that every contention by force between two nations, in external matters, under the authority of their respective governments, is not only war, but public war.”

² For example, the “Phoney War” from September 3, 1939, when France declared war on Germany, until May 10, 1940, when Germany invaded the Netherlands, Belgium and Luxemburg.

³ For example, pacific reprisals, border clashes.

⁸ Other types of definition include (a) the “common meaning” definition (for example, II Westlake, International Law 1 (Cambridge, 1913) and II Oppenheim, International Law 172 (London, 1906), but this is of little use, as there is no common meaning of the word “war,” and because any such meaning will be too imprecise for the complex situations the law has to face; and (b) the “etymological” definition (for example, Olivant, R., Derecho International Publico 277 (Turin, 1906),Google Scholar which is, again, imprecise and devoid of legal character.

¹³ Similar concern arose when it was realized that as the U.N. Charter is incompatible with the “concept of war,” and as U.N. forces can only be established and used within the limits of the Charter, the laws of war cannot apply to U.N. peace-keeping operations: see Simmons, R., Legal Problems Arising from the United Nations Military Operations in the Congo 172 (The Hague, 1968).CrossRefGoogle Scholar

¹⁷ As when the Texas Court of Criminal Appeals held that a half-hour skirmish between tiny sections of the Mexican and United States armies, in June 1916, constituted war in the meaning of Article 3 of the Annex to Hague Convention IV of 1907, and captured Mexican soldiers were thus to be treated as prisoners of war: Grob, op. cit. supra note 16, at 218.

²¹ In addition, it must be remembered that the same term, in different contexts, will mean different things. Thus, a particular level of “armed force” sufficient to justify the invocation of sections of the Geneva Conventions of 1949 might not suffice for the 1954 Hague Convention on the Protection of Cultural Property.
