President Biden is not holding PM Netanyahu's hand and skipping along. The recent press releases by PM Netanyahu are proof that he's not getting everything he wants or blind support from the US. Diplomacy is rarely played out in public. What's seen in public is either theater or after-the-fact stuff. Public protests may be gumming up the works/the outcomes they supposedly want.
President Biden stepping down after the NATO Summit allows him to be the senior statesman and continue efforts with Israel to end the mess PM Netanyahu has made and continues to make in Gaza.
