Netanyahu has long trumpeted his ties to Trump. But the president is sidelining him on urgent issues like the Iran nuclear talks and the conflict with Houthi rebels.

As President Donald Trump sets out for the Middle East in the first international trip of his second administration, signs of disagreements have emerged between the U.S. leader and one of the men who most enthusiastically welcomed his return to office.

The first sign of Trump’s irritation came during their White House press conference in April. Trump did not reverse the 17 per cent tariffs he had slapped on Israel and pointed out that Israel gets $4bn a year in aid.
