USA HISTORY

Detailed explanation-1: -Although Israel has possessed nuclear weapons since the 1960’s, it maintains a policy of nuclear opacity, never officially confirming the existence of its nuclear program. Accordingly, Israel has never signed the NPT.

Detailed explanation-2: -Four UN member states have never accepted the NPT, three of which possess or are thought to possess nuclear weapons: India, Israel, and Pakistan. In addition, South Sudan, founded in 2011, has not joined.

Detailed explanation-3: -It was France, in particular, enraged by the failure in 1956, that began building Israel’s bomb.

Later, other western countries, including Britain, helped.
