Carlo Lazo won a Bronze Star for providing medical aid to his fellow soldiers under fire from snipers and artillery in Iraq. But he can't do anything to help his ailing 16-year-old son. That's because the boy lives in Cuba, and the U.S. government has put tougher sanctions on that country aimed at restricting the flow of dollars into Cuba by limiting Cuban-Americans from visiting family members. People such as Lazo used to be allowed one visit per year. Now, it's one every three years, and Lazo won't be eligible to visit again until 2006.
