Last December, when I interviewed the leader of Israel’s left-leaning Labor Party, Isaac “Bougie” Herzog, at the Brookings Institution’s Saban Forum, he said, in reference to nuclear negotiations with Iran: “I trust the Obama administration to get a good deal.”

In a telephone call with me late last night, Herzog’s message was very different. The deal just finalized in Vienna, he said, “will unleash a lion from the cage, it will have a direct influence over the balance of power in our region, it’s going to affect our borders, and it will affect the safety of my children.”

Iran, he said, is an “empire of evil and hate that spreads terror across the region,” adding that, under the terms of the deal, Iran “will become a nuclear-threshold state in a decade or so.” Iran will take its post-sanctions windfall, he said, and use the funds to supply more rockets to Hezbollah in Lebanon, more ammunition to Hamas in Gaza, and “generally increase the worst type of activities that they’ve been doing.”
