The U.S. military is reportedly preparing for possible action against Cuba. Reports say the U.S. Army Reserve is examining units that could be ready in just three months for a potential military move. A former U.S. national security advisor has said he supports ending the Cuban government, calling it a 'great thing' for the Western Hemisphere. Meanwhile, U.S. sanctions are seen as a problem for the Cuban economy, making things more difficult between the two countries.
