A televised exchange with Brett McGurk, the Middle East advisor kept on by both Biden and Trump, shows how little Washington's Israel policy changed across administrations — bad news for anyone expecting accountability.

• McGurk said the White House nearly took "draconian" steps against Israel after an Israeli strike killed World Central Kitchen aid workers, but dropped the idea when Iran launched missiles.

• Left unsaid: Iran only fired because Israel had just bombed its embassy in Damascus, and Tehran warned Washington in advance so the missiles could be shot down. Nobody died.

• Instead of penalties, Congress passed $26 billion in military aid to Israel that same month, with support from both parties and a push from Biden.

• The pause on 2,000-pound bombs was a delay, not a cutoff, and Trump lifted it on taking office.

• McGurk has served under Bush, Obama, Biden and Trump — the clearest sign that US policy on Israel does not shift with elections.

Outlook: With the same advisors in place and the same unchallenged talking points on air, expect the identical playbook to be used to build the case against Iran.
