Banksy has shown great courage by travelling to one of the world's most talked about conflict zones and creating politically controversial works of art. We should encourage him to explore his art in some of the less talked about conflict zones such as Yemen, Iraq, Syria, Mexico, Sinai, Myanmar, West Papua, Chechnya and Dagestan, Somalia, Mali. The authorities and other parties to conflict will , I'm sure , appreciate the opportunity to engage in dialogue through art and offer him the hospitality usually shown to the politically active radical.
