我们也不知道伊朗四分五裂的领导层是否已经决定研发核武器，还是只是暂时停一段时间，算计着本国可以在获取核武器的过程中获得许多好处，又不用承受真正获得核武器后的风险和代价。
We also do not know whether Iran’s divided leadership has decided to develop nuclear weapons, or to stop just short, calculating that the country could derive many of the benefits of possessing nuclear weapons without running the risks or incurring the costs of actually doing so.
