What really lay behind this picture choice of Benjamin Netanyahu speaking at the UN General Assembly last week?

In the course of his address, the Israeli premier accidentally appeared to ape the pose of Adolf Hitler in the notorious arm-raised Nazi salute.

Officers of the Anti- Defamation League have challenged the controversial photo published by the Associated Press and Reuters, but an AP spokesperson merely said the photos were “among a wide variety of Prime Minister Netanyahu during his speech — 27 in all — that were taken and distributed by AP”.
