The Pentagon Nuclear Posture Review was completed in January and "leaked" to the Los Angeles Times, around two weeks ago. It lists Russia, China, Libya Iran, Iraq, North Korea, and Syria as potential targets against which first strike nuclear attacks could be launched. It also suggests the use of "smaller" nuclear weapons in specific battlefield situations! One possible justification for their use could be "in the event of surprising military developments"
Only two, perhaps three, of these states possess a nuclear capability, and a posture which threatens the others fundamentally undermines the long-adhered to non-proliferation treaty, and the pledge made by President Kennedy, along with the UK, China, Russia, and France, never to use nuclear weapons against a non-nuclear power. This pledge has been renewed at all subsequent NPT reviews. A review is due next month in New York at the UN.
