<P> Some critics say that the embargo actually helps the regime more than it hurts it, by providing it with a bogeyman for all of Cuba's misfortunes . Hillary Clinton publicly shared the view that the embargo helps the Castros, noting that "It is my personal belief that the Castros do not want to see an end to the embargo and do no want to see normalization with the United States ." Clinton said in the same interview that "we're open to changing with them ." </P> <P> In a 2005 interview, George P. Shultz, who served as Secretary of State under Reagan, called the embargo "insane". Daniel Griswold, director of the Cato Institute's Center for Trade Policy Studies, criticized the embargo in a June 2009 article: </P> <P> The embargo has been a failure by every measure . It has not changed the course or nature of the Cuban government . It has not liberated a single Cuban citizen . In fact, the embargo has made the Cuban people a bit more impoverished, without making them one bit more free . At the same time, it has deprived Americans of their freedom to travel and has cost US farmers and other producers billions of dollars of potential exports . </P> <P> Some American business leaders openly call for an end to the embargo . They argue, as long as the embargo continues, non-U.S. foreign businesses in Cuba that violate the embargo, do not have to compete with U.S. businesses, and thus, will have a head start when and if the embargo is lifted . </P>
