 随着奥巴马总统在 2009 年发表布拉格讲话，美国启动了核保安峰会进程。这一元首级论坛于 2010 年在华盛顿举行第一次会议，随后于 2012年在首尔、2014 年在海牙举行了峰会。奥巴马总统将于 2016 年在美国主办第四次峰会。这些峰会提高了人们对全世界核保安重要性的认识，导致了以下方面的努力：(1)减少全球危险核材料的数量，(2) 加强核材料和放射源的保安，以及(3)加强国际合作以减轻核恐怖主义构成的威胁。
• The United States launched the Nuclear Security Summit process with President Obama’s Prague Speech in 2009. This head-of-state level forum first met in 2010 in Washington, with subsequent Summits in Seoul in 2012 and The Hague in 2014. President Obama will host a fourth Summit in the United States in 2016. The Summits have raised awareness on the importance of nuclear security worldwide, and have resulted in efforts to (1) reduce the amount of dangerous nuclear material globally, (2) improve security of nuclear material and radioactive sources, and 3) improve international cooperation to reduce the threat posed by nuclear terrorism.
