The Trump administration's recent steps in the Israeli-Palestinian conflict should surely lay to rest any doubts about the enormous, and dangerous, power of the Israel lobby in Washington.
Under Trump, the lobby has shown it can wield unprecedented influence – even by its usual standards – in flagrant disregard for all apparent US interests.
First, there was the move this month of the US embassy to Jerusalem, not quietly but on the 70th anniversary of the most sensitive day in the Palestinian calendar, Nakba Day. That is when Palestinians commemorate their mass expulsion from their homeland in 1948.
By relocating the embassy, Trump gave official US blessing to tearing up the 25-year-old peace process – and in choosing Nakba Day for the move, he rubbed the noses of Palestinians, and by extension the Arab world, in their defeat.
