Haiti–United States relations are bilateral relations between Haiti and the United States. Succeeding U.S. presidents refused to recognize Haiti until Abraham Lincoln. The U.S. tried to establish a military base in Haiti and invaded. It withdrew in 1934 but continued to intervene in Haiti during subsequent decades. According to the 2011 U.S. Global Leadership Report, 79% of Haitians approved of U.S. leadership, with 18% disapproving and 3% uncertain, the highest rating for any surveyed country in the Americas.
