Donald Trump's patience with Benjamin Netanyahu is all but exhausted. Trump is deeply frustrated and resentful of Netanyahu for selling him a bill of goods on Iran that's turning out to be the worst purchase of his political life. Up there in the category of George W Bush's Iraq War.
Trump can't get out soon enough and Bibi doesn't want to, which makes for an untenable situation. Thus, apocalyptic threats from POTUS against Iran one day and visions of diplomacy the next. The cycle has repeated so many times, the world doesn't take the tiresome tirades and climbdowns seriously any more. No one can eat that many TACOs.
