And Europe Will Be Stunned is a deeply stirring and contentious film trilogy by the Dutch-Israeli artist Yael Bartana, soon to open in Britain on its European tour. Each film is enough to disturb; together they are peculiarly subversive. I do not know exactly what they might mean to Jewish, Israeli or Palestinian viewers, still less to a Polish audience watching some of the scenes unfolding on the site of the Warsaw Ghetto itself. But my sense is that an anxious concern for other people's reactions is at least part of the trilogy's content.

In the first film, Nightmares (2007), a political leader strides into a Warsaw stadium to rally the crowds. "Let the 3 million Jews that Poland has missed… return to Poland, to your country," he urges, acknowledging Poland's antisemitic history but arguing that Jews and Poles should come together once more to extinguish the hatred.
