But uranium enrichment makes a lot of sense if you want a nuclear weapon; indeed, for that purpose, enrichment is indispensable. Moreover, Iran is building a heavy-water reactor, supposedly for research purposes, but which is also needed to build a plutonium bomb.
但如果要制造核武器的话，那么进行铀浓缩就合情合理了；事实上，浓缩是实现这一目标的必经之路。此外伊朗正在建设一个重水反应堆，虽说是为了科学研究，但也是制造原子弹所需的设备。
