JERUSALEM — A “catastrophe.” A “bad deal.” An agreement that “throws a lifeline to the murderous regime in Tehran.”

Among Israeli Prime Minister Benjamin Netanyahu’s supporters and critics alike, in the media and on social media, the mood was clear as Israelis woke up Monday to news of a peace agreement between the United States and Iran: President Donald Trump’s deal is not one that many in Israel like. Iran, they say, will remain a threat.
