by observers to make concrete moves toward this goal. The finished 2010 policy renounces development of any new nuclear weapons such as the bunker-busters proposed by the Bush administration, and for the first time rules out a nuclear attack against non-nuclear-weapon states who are in compliance with the Nuclear Non-Proliferation Treaty. This rule specifically excludes Iran and North Korea. As part of the implementation of the 2010 Nuclear Posture Review, the US Government is reviewing its nuclear deterrence requirements and nuclear plans to ensure that they are aligned to address today's threats. Rose Gottemoeller, US Acting Undersecretary of State for Arms Control and International Security, said in early June 2012 that the United States was considering what forces the United States needed to maintain for strategic stability and deterrence, including extended deterrence and assurance to US Allies and partners. Based on this analysis the United States would develop proposals for potential further reductions in its nuclear stockpile. 2018 NPR With Donald Trump's election came a new nuclear posture review headed by Secretary of Defense James Mattis. The 2018 NPR maintains the need for a nuclear triad in the US defense strategy. There are a variety of options that have been proposed by the 2018 NPR. One of the statements made include a need to close a gap in the nuclear arsenal with low-yield nuclear weapons. This suggests that the US would consider using nuclear weapons if necessary on a smaller-scale regional conflict rather than all-out nuclear war. Other things to note from the 2018 NPR include a need to develop sea-launched cruise missiles (SLCMs) to bolster the SSBN portion of the triad. The review also states the US's intention to not ratify the CTBT and rejects the idea of the Treaty on the Prohibition of Nuclear Weapons. Despite these recommendations and stances, the 2018 NPR is argued to be similar rather than different from previous NPRs. The NPR maintains that nuclear weapons are still meant to serve as a deterrent, which is the goal of these proposed actions to modernize the US nuclear arsenal.
