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 previous U.S. national security official has said he supports ending the Cuban government, calling it a 'great thing' for the Western Hemisphere. Meanwhile, U.S. sanctions are seen as an obstacle for Cuban economic changes, making things worse between the two countries.
