India

India has formally declared itself a nuclear weapon state. New Delhi is likely to have manufactured weapons-grade plutonium for at least 110-120 warheads, which are not deployed but in central storage.

Israel

Israel is widely understood to possess a sizeable nuclear arsenal but maintains a policy of nuclear ambiguity. Their stockpile is estimated to be 80 warheads. Based on estimates of the plutonium production capacity of the Dimona reactor, Israel has enough plutonium for approximately 100-200 advanced nuclear explosive devices.
