Abstract
A few days after announcing further improvements in its nuclear program, Iran refused again to answer questions from the IAEA inspectors and to allow them access to a site suspected of harboring military nuclear activities. International actors are divided on the measures to be undertaken. The military option is on the table but Israel does not obtain the consent of the majority of great powers who prefer the policy of sanctions /negotiations. The question is whether, after this succession of provocations, the 5 +1 group will accept the Islamic Republic offer to resume negotiations.
Key words : Iran, nuclear, sanctions, Security Council, China and Russia, Israel, United States
