The U.S. military is reportedly getting ready for possible action against Cuba. Reports say the U.S. Army Reserve is looking at units that could be ready in just three months for a possible operation. A former U.S. national security advisor has said he supports removing the Cuban regime, 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.
