President Obama made history by coming to office with the promise of working towards a nuclear weapons-free world. Envisioning a new non-proliferation momentum, Obama promised to revive the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) system and create nuclear security and energy architectures that will secure nuclear materials and make proliferation difficult. A year later, Obama realised the difficulties of selling his vision to his bureaucratic-military establishment, which resisted efforts to reduce the role of nuclear weapons while pushing for nuclear modernisation.

The Iranian nuclear stand-off is still a major issue in global politics. From international players like the European Union, the United States and the United Nations, to individual states, almost each country has its own stake in the issue.

The deal has changed the nature because the one-sided dialogue between the international community and Iran is no longer relevant.
