If such a country, many Russians reason, wants to acquire nuclear weapons, it probably will. Bombing known facilities would set back the nuclear program, but would also ensure that Iran eventually gets the bomb, to deter any such attacks in the future. The only way to prevent Iran from having nuclear weapons, the Russians believe, is for the international community to craft a deal under which Iran would agree to stop after achieving a nuclear-weapons capability, while the world’s leading powers would agree to reintegrate Iran into the international community by dropping sanctions, unfreezing assets and admitting Iran into the World Trade Organization.
