However, a principal duty set forth in the Harvard Draft was that a neutral should be impartial (Art. 4) which, though not a new concept, perhaps amounts to an implicit acknowledgment of the inadequacy of the previously delineated definitions and rules of neutrality.

²⁰ “The Committee is of the opinion that the unilateral action of the defaulting State cannot create a state of war. … If it is admitted that a state of war does not exist, ipso facto, between the defaulting State and the other Members of the League, it follows that those relations, the severance of which is not provided for by Article 16, may continue to exist.” Id. at p. 17.

This, however, it should be noted, remains a right limited by Art. 16.

²⁸ In his address at the Inter-American Bar Association meeting of March 27, 1941, at Havana, the then Attorney General of the United States, Robert H. Jackson, said: “The Treaty for the Renunciation of War and the Argentine Anti-War Treaty deprived their signatories of the right of war as an instrument of national policy or aggression and rendered unlawful wars undertaken in violation of their provisions. In consequence, these treaties destroyed the historical and juridical foundations of the doctrine of neutrality conceived as an attitude of absolute impartiality in relation to aggressive wars. It did not impose upon the signatories the duty of discriminating against an aggressor, but it conferred upon them the right to act in that manner.” This Journal, Vol. 35 (1941), p. 354.

The Arab League attitude was apparently dictated by resentment against United Nations’ handling of the Palestine question and does not necessarily indicate a legal position by these states that they could not be bound. Lebanon announced support on July 7, however (N. Y.

Non-Members complying: Federal Republic of Germany, Italy, Japan, Laos, Spain, Viet Nam.

Ecuador, Panama, Austria, Finland, and Jordan merely acknowledged the resolution. The Soviet Union and the Soviet satellites believe the resolution to be illegal. See supra, footnote 101 (Albania, Hungary and Rumania agreed with this position).

Burma and India abstained on the vote on the resolution. Both report no trade with China in the banned items (as does Cambodia) but neither seems very cordial to the embargo. See Reports from Governments on Measures taken in accordance with General Assembly Res. 500 (V), U.N. Docs. A/1841, July 12, 1951; A/1841, Add. 1, July 25, 1951; A/1841, Add. 2, Aug. 9, 1951; A/1841, Add. 3, Sept. 28, 1951; A/1841, Add. 4, Oct. 23, 1951; A/1841, Add. 5, Dec. 12, 1951.

¹⁰³ Supra, footnote 92.

¹⁰⁴ On Dec. 2, 1951, the Communist negotiators for a cease-fire in Korea suggested that “neutrals” be used to police the proposed armistice (N. Y. Times, Dec. 3, 1951, p. 1, col. 8). On Dec. 5, they named Poland and Czechoslovakia as “neutrals” of their choice and conceded that Denmark, Sweden and Switzerland might be considered “neutrals” (ibid., Dec. 6, 1951, p. 1, col. 1). All except Switzerland are U.N. Members and Denmark and Sweden have contributed a hospital ship and a military hospital to the action. On Dec. 11, the U.N. negotiators accepted “neutral” control (ibid., Dec. 12, 1951, p. 1, col. 8) and the United States, on Dec. 15, notified Switzerland, Sweden and Norway (rather than Denmark) that they would be acceptable to the U.N. Command, though they were referred to as “non-belligerent” rather than “neutral” (ibid., Dec. 15, 1951, p. 2, col. 4).

The more recent plans evolved by the U.N. Command and the Communist forces for a truce also depend on the use of “neutral” states. In April, 1953, the U.N. proposed a nation such as Switzerland to take custody of prisoners refusing repatriation (ibid., April 15, 1953, p. 1, col. 7), but the Communists rejected Switzerland as not a “real neutral” since it had been earlier nominated by the “Allies” as one of the countries to supervise an armistice (ibid., April 27, 1953, p. 1, col. 8). On May 2, the Communists listed India, Pakistan, Burma and Indonesia as Asian nations considered “neutral” in the Korean war (all being U.N. Members) and said that Switzerland, Sweden, Poland and Czechoslovakia were still considered neutral too (ibid., May 2, 1953, p. 1, col. 8). On May 4, the U.N. Command asked for the acceptance of Pakistan “as the neutral nation,” and insisted again on turning the captives over to the custody of a “neutral” in Korea rather than moving them to the neutral nation (ibid., May 4, 1953, p. 1, col. 8, and May 5, 1953, p. 1, col. 8; see id., p. 3, col. 1, for the views of the Asian nations). On May 7, the Communists proposed that a 5-nation “neutral” repatriation commission consisting of Czechoslovakia, Poland, Switzerland, Sweden and India take custody in Korea of prisoners who refuse to go home (ibid., May 7, 1953, p. 1, col. 8), and on May 13, the U.N. Command sharply revised the Communist plan but accepted the 5-nation commission, calling it a “prisoner of war repatriation commission” and not referring to the nations as “neutrals” (ibid., May 14, 1953, p. 4, col. 2 ff.) It was also insisted that India alone should send troops to Korea and should have operational control of all detention forces. This proposal was termed “absolutely unacceptable” by the Communists (ibid., p. 4, col. 6), but on June 8 an agreement along these lines was arrived at (Department of State Bulletin, Vol. 28, No. 730, p. 866.)

The action of the U.N. Command in this matter is obviously one of expediency and does not detract from the arguments above presented. If the employment of the services of certain Powers can bring the conflict to an honorable conclusion, it might well prove a wise policy for the U.N. Command—no precedent is necessarily involved, since this is not in fact a full action by the “unified forces of the world” (as indicated by the earlier Communist suggestion that the Soviet Union serve as a “neutral” too). It is unfortunate, however, that the U.N. has used the term “neutral” for non-participants without making clear that, certainly for Members, old-style neutrality could not be considered as consonant with Charter obligations.

¹⁰⁵ Their persistence is recognized in the four conventions signed on behalf of most of the world’s nations at Geneva on Aug. 12, 1949, each of which makes numerous references to “neutrals” and “neutral Powers”; e.g., Condition of the Wounded in the Field, Arts. 4, 43; Condition of the Wounded at Sea, Arts. 5, 32; Protection of Civilians, Arts. 4, 11; Treatment of Prisoners of War, Arts, 10, 110, 111, U.
