Despite the embargo, the U.S. does do business with Cuba. Last year, according to the Census Bureau, the U.S. exported nearly $300 million worth of products to Cuba; nearly all (96.2%) of that was in the form of meat and poultry, soybeans, corn, animal feed and other foodstuffs. The exports are permitted under a 2000 law that modified, but did not repeal, the U.S. embargo; under it, Cuba can buy certain agricultural products, medicines and medical devices from the U.S., but must pay in cash.

Some "siege", some "blockade", eh!
