Rarely has a move by the U.S. government to impose its political views on other countries' economies aroused as much anger as has the Cuban Liberty and Democratic Solidarity (Libertad) Act of 1996, widely known as the Helms-Burton Act. President Clinton originally opposed the Act, but signed it into law in March 1996, following the downing by the Cuban Air Force of two light planes flown by members of an anti-Castro organization based in the United States.
