Saving Transatlantic Cooperation and the Iran Nuclear Deal. A View from Europe and the United States
Transatlantic differences over the future of the Iran nuclear deal – or the Joint Comprehensive Plan of Action (JCPOA) of July 2015 – are damaging a nuclear accord that all parties, except the United States, see as delivering on its purpose. They also increase the risk of Washington and European capitals working at cross-purposes vis-à-vis Iran and broader regional policies. To avoid such a scenario, the E3 (France, Germany, United Kingdom)/European Union (EU) and the United States need to set up new channels of communication to avoid a transatlantic rift, to attempt – if at all possible – to preserve the Iran deal, and to secure its benefits for regional and global security.

After the world entered the nuclear age, civilian and military organizations have witnessed the slow emergence of nuclear cultures, defined as the set of values and knowledge, shared among the national security community, about the relative importance of nuclear weapons in the country’s defense posture, the distinctive features of nuclear weapons in terms of security, safety and operational requirements, and the workings of deterrence.

La prueba nuclear norcoreana refuerza el papel de EE UU en Asia
Corea del Norte ha tratado esta semana de aumentar la presión para ser reconocida como una potencia nuclear con la prueba del pasado miércoles en la que aseguraba que empleó una bomba de hidrógeno. Y ha introducido un nuevo elemento en el gran juego de alianzas estratégicas y comerciales que Estados Unidos y China disputan en el siglo XXI en Asia, un tablero de ajedrez que representa el 38,8% del PIB mundial. La prueba nuclear ha dejado en evidencia la falta de control de Pekín sobre Pyongyang y ha reforzado el papel de Washington como garante de la seguridad en la región.

North Korea's Nuclear Weapons Development: Implications for Future Policy
Despite the resumption of high-level diplomatic contact between Washington and Pyongyang in late 2009, realization of a non-nuclear Korean Peninsula remains a very remote prospect, with the DPRK insisting that a peace agreement between the U.S. and North Korea and hence the cessation of "hostile DPRK-U.S. relations" are necessary before any consideration of denuclearization.
