Iran came to talks in Moscow last week (June 18-19) prepared to discuss stopping enriching uranium to 20% but refused two other conditions that could have led to a partial agreement in the nuclear standoff.
Briefings by diplomats whose countries took part in the talks portrayed the meetings as a "dialogue of the deaf," with the two sides trading widely divergent proposals. However, Iran’s chief nuclear negotiator did express willingness to discuss one key step requested by the five permanent members of the UN Security Council plus Germany (P5+1): stopping enrichment of uranium to 20% U-235, the isotope that gives uranium its explosive power.
