In fact, the Reagan Administration was sharply divided on the issue. Meeting on 5 April, Haig and Assistant Secretary of State for Political Affairs Lawrence Eagleburger favoured backing Britain, concerned that equivocation would undermine the NATO alliance. Assistant Secretary of State for Inter-American Affairs Thomas Enders, however, feared that supporting Britain would undermine US anti-communist efforts in Latin America. He received the firm backing of United States Ambassadors to the UN Ambassador Jeane Kirkpatrick, Haig's nominal subordinate and political rival. Kirkpatrick was guest of honour at a dinner held by the Argentine ambassador to the United States, on the day that the Argentine armed forces landed on the islands.
