He’s been back messing with the Chosen People who decided that the way to win the hearts and minds of their Palestinian subjects was to build a Stasi-style wall straight thru places like Bethlehem.
He’s done that before, of course (more here and here), and it’s just as excellent as always.
The project is called Santa’s Ghetto. [Edit: there’s now an official Banksy page that’s worth a visit — especially if you have a few hundred thousand floating around and want an original banksy for the walls of your S&M dungeon or something].
