Instant Messaging – Why UN Covered Its Guernica Reproduction?

Was it sensitive to the message? “The continuing sensitivity to Guernica exemplified by the U.N. cover-up may remind us that modern art is poor in images glorifying just military action, though rich in images of the horrors and injustices of war. Further back in history, of course, there are numerous celebrations of the triumph of righteous might.”
