I do agree with Bernie that we as a country should not be invading countries around the globe. Providing aid is one ting, overthrowing leadership in nations is another.
And the only thing I ever agreed with that Obama did was normalizing relations with Cuba. We trade with China and Vietnam, two communist nations, both countries that we had men fighting their people in two wars, the Chinese in the Korean War and of course the Vietnam War.
While we embargoed Cuba, the primary beneficiary was Canada. Made no sense to me.
Bernie is a bit over the top on how well the Cuban people are living. If they were doing so well, we would not have a steady stream of people fleeing Cuba to come to the USA through the years.
