Under the Nuclear Non-Proliferation Treaty, nuclear states have pledged to destroy all their nuclear weapons. In addition, they are legally obliged not only to refrain from any attempt to build nuclear weapons, but also to refrain from transferring such weapons to other countries, deploying them outside their territory, or cooperating with other governments to build nuclear weapons.

After decades of non-compliance with these legal obligations, the nuclear armed states have reaffirmed their commitment to take effective practical steps to destroy nuclear weapons in the final documents of the NPT Review Conferences of 1995, 2000 and 2010.

Iran's proposed resolution also highlights the need to provide security assurances to non-nuclear states that they will not use or threaten to use nuclear weapons against them.
