Last week, as Washington was melting down over the leaked contents of Donald Trump’s memorandum of understanding with Iran, Israelis were reacting in kind. Israel was not a party to the negotiations—hardly surprising, given Benjamin Netanyahu’s overt opposition to ending the conflict—but the Israelis were particularly irate on two fronts. Not only did the deal offer nothing on the issue of reining in Iran’s proxies, like Hezbollah, Hamas, and the Houthis, but it also did something far worse: By accepting the Iranian framework that a ceasefire must include Israel and Hezbollah, the M.O.U. essentially relegated Israel to the status of a proxy itself.
