【Negotiations Failed to Break the Deadlock, Iran Insists That Israel's Cessation of Attacks is a Prerequisite for Talks with the U.S.】 As the Trump administration weighs whether to join Israel in its strikes against Iran, negotiations between Iran and European leaders have not brought Iran closer to making concessions to end the struggle over its nuclear program. European countries have joined the Trump administration in demanding that Iran stop its nuclear fuel enrichment activities, increasing pressure on Tehran to agree to terms it rejected in this year's nuclear negotiations. Arab and European officials familiar with the talks said that Iran's foreign minister continued to insist on Friday that Iran has the right to enrich uranium. He also asserted that Iran would not re-engage in nuclear talks with the U.S. until Israel ceases its attacks. He stated after the talks: 'Once the aggression stops, the aggressor is held accountable for the crimes committed, and Iran is prepared to reconsider diplomatic means.' On the other hand, Israel showed no signs of being ready to halt the offensive actions that began a week ago. The Israeli Chief of Staff stated on Friday that Israel must be prepared for a prolonged conflict with Iran.
