Those commitments ended in 2005, owing to the continued insistence by the EU, backed by the US, that Iran abandon uranium enrichment entirely. This stance disregarded the “inalienable right,” clearly acknowledged in the Nuclear Non-Proliferation Treaty (as much as one might wish otherwise, in an ideal world), of NPT parties to engage in all stages of the nuclear fuel cycle as part of a peaceful nuclear energy program.
这些承诺结束于2005年，原因是欧盟在美国的支持下坚持要求伊朗完全放弃铀浓缩。这一立场无视核不扩散条约所明确承认的“不可剥夺的权利”（在理想世界中你也只能期待这么多了）。核不扩散条约规定，签署国可以进行各阶段核燃料循环，只要出于和平核能用途目的。
