Cuba isolated - "all your own fault" say Americans

I couldn't help laughing at a report I heard on the World Service at around 3am. Apparently Cuba are building a wall to block out the sight of an electronic message board erected by the USA. World Serice news quoted an American spokesperson as saying that by doing this, Cuba were "isolating themselves from the rest of the world". Hello? American spokesperson? Concerned about Cuba isolating themselves? Shurely shome mishtake?
