Israel is believed to have acquired nuclear weapons around 1967 but has never openly tested or formally acknowledged possessing them.

Notes on verification

Well-corroborated by multiple independent sources including Wikipedia, Foreign Policy, arms control organizations, and nuclear history experts. The core claim about timing (~1967) and policy of non-acknowledgment/non-testing is consistent across sources. Minor complicating nuance exists regarding the disputed 1979 Vela incident, but this doesn't contradict the 'openly tested' framing.
