Iran Special: Why Both Sides Shifted in Nuclear Talks --- And What Comes Next (Dalton)
Each side moved some way. Earlier each had escalated in the hope of bringing extra pressure to bear to shift any negotiations their way. The Iranians started 20% enrichment, and then moved it from exposed Natanz to safer Fordow, underlining the perils for the Six in delaying a move to a more flexible and hence constructive position. And ever-tighter financial sanctions and the partial oil embargo appear to have led Iran to moderate its defiance and allow itself the option of a change of policy.
It will be tough turning these preliminary moves into a deal. The first requirement for the Six is to recognize in practise that distrust is two-way. They must be seen to negotiate in good-faith on nuclear issues and not to hold regime change up their sleeves.
