Which country claimed nuclear for joining NPT?
North Korea
The Democratic People’s Republic of Korea (or better known as North Korea), joined the NPT in 1985 and had subsequently signed a safeguards agreement with the IAEA. However, it was believed that North Korea was diverting plutonium extracted from the fuel of its reactor at Yongbyon, for use in nuclear weapons.
What does the word non proliferation mean?

Why is the NNSA important?
NNSA ensures the United States maintains a safe, secure, and reliable nuclear stockpile through the application of unparalleled science, technology, engineering, and manufacturing. NNSA works to prevent nuclear weapon proliferation and reduce the threat of nuclear and radiological terrorism around the world.
Who runs the NNSA?

What is the ultimate goal of the NPT?
nuclear disarmament
The ultimate goal of the NPT is nuclear disarmament thus preventing wider diffusion of nuclear weapons. The NPT, a multilateral treaty, aims at limiting the spread of nuclear weapons including three elements: (1) non-proliferation (2) disarmament (3) peaceful use of nuclear energy.
Who is not on NPT?
Non-signatories. Four states—India, Israel, Pakistan, and South Sudan—have never signed the treaty. India and Pakistan have publicly disclosed their nuclear weapon programs, and Israel has a long-standing policy of deliberate ambiguity with regards to its nuclear program (see List of states with nuclear weapons).
