It is unlikely, but hardly impossible, that Israel could decide to use nuclear weapons first in a future conflict. The best way to prevent this from happening is to limit the reasons why Israel might want to use these weapons, which is to say preventing the further proliferation of nukes. If Israel ever does use nuclear weapons in anger, it will rewrite the diplomatic and security architecture of the Middle East, and also the nonproliferation architecture of the world as a whole.
Israel’s nuclear arsenal is the worst-kept secret in international relations. Since the 1970s, Israel has maintained a nuclear deterrent in order to maintain a favorable balance of power with its neighbors. Apart from some worrying moments during the Yom Kippur War, the Israeli government has never seriously considered using those weapons.
The most obvious scenario for Israel to use nuclear weapons would be in response to a foreign nuclear attack. Israel’s missile defenses, air defenses, and delivery systems are far too sophisticated to imagine a scenario in which any country other than one of the major nuclear powers could manage a disarming first strike. Consequently, any attacker is certain to endure massive retaliation, in short order. Israel’s goals would be to destroy the military capacity of the enemy (let’s say Iran, for sake of discussion) and also send a message that any nuclear attack against Israel would be met with catastrophic, unimaginable retaliation.
