US President Joe Biden said last month he would soon have a "come to Jesus" moment with Israeli Prime Minister Benjamin Netanyahu over the war in Gaza.
And Thursday it happened during an unusually frank and direct phone call, which put Netanyahu on notice about a possible shift in US policy.
The trigger was an Israeli drone strike in Gaza on April 1 that killed seven aid workers for World Central Kitchen, a charity group run by celebrity chef Jose Andres, which has since suspended its operations in Gaza.
Biden said he was “outraged and heartbroken” by the deaths. A flurry of official US statements and readouts kept up the line of "outrage" over the killings.
