Florida Sen. Marco Rubio blasted the Obama administration recently for relaxing restrictions on travel and trade with Cuba. The change in policy, Rubio argued, ignores human rights issues that continue to exist in Cuba. Further, he said, our expanded interaction with the country will not inspire the Castro regime to change its ways. Sending tourists to Havana will not make life any easier for pro-democracy nationals. Lowering trade barriers will not force the Cuban government to curtail its use of violence in dealing with opponents or critics.
