Why the world should worry about Israel’s nuclear doctrine

The threshold the Israeli authorities have set for the use of a nuclear weapon is dangerously low.Palestinian political analyst and playwright.Published On 22 Mar 2026For decades, the world has treated Israel’s nuclear arsenal as an awkward secret — something everyone knows exists but few are willing to discuss openly. Israel has never officially acknowledged possessing nuclear weapons, yet it is widely understood among security experts that the country maintains a significant nuclear capability.Estimates from institutions such as the Stockholm International Peace Research Institute suggest Israel possesses roughly around 80 nuclear warheads, along with delivery systems that could include aircraft and ballistic missiles. The policy governing this arsenal is known as “nuclear opacity.”Israel neither confirms nor denies the existence of its weapons. In practice, this ambiguity has allowed the international community to avoid confronting a difficult question: under what circumstances would Israel actually use them?That question matters more today than at any point in recent decades, as the United States and Israel wage a dangerous war on Iran. On Saturday, Iran struck the Israeli city of Dimona which houses a key nuclear facility, demonstrating that it can retaliate for attacks on its own nuclear sites.Israeli strategic thinking has long been shaped by the fear of an existential threat. Unlike most nuclear states, whose doctrines revolve around deterrence or competition with other nuclear powers, Israel’s security narrative is rooted in the belief that the country could face destruction if a war turns decisively against it. Israeli leaders have repeatedly framed regional conflicts — from the wars of 1967 and 1973 to present confrontations with Iran and armed groups in Gaza and Lebanon — as struggles for national survival. That mindset matters enormously when nuclear weapons are involved.
