Hi
Perhaps the best answer to your question was offered by Picasso himself in an anecdote (perhaps spurious) of his answer to a question by a Gestapo who asked him pointing to Guernica_ “Did you do that” to which Picasso answered _ “No Monsieur, you did”
Apart from a masterpiece of Cubism, Guernica is a monument, pointing to “man’s inhumanity to man” and the cruelty and injustices of war
