US Secretary of State Mike Pompeo has said he reviewed reports of Iranian plans to increase uranium enrichment capacity, stressing that Washington would not allow Tehran to develop nuclear weapons, and Tehrans moves to reinstate uranium enrichment provoked resentment among Europeans trying to salvage the JCPOA and protect their companies from US sanctions.  The Joint Comprehensive Plan of Action, known commonly as the Iran nuclear deal or Iran deal, is an agreement on the nuclear program of Iran reached in Vienna on July 14, 2015 between Iran, the P5+1, and the European Union. However, US President Donald Trump pulled out from the deal on May 8, citing Iranian aggressive behavior and shortcoming of inspection access.  "We’re watching reports that Iran plans to increase its enrichment capacity," Pompeo wrote in a Twitter post on Wednesday. "We won’t allow Iran to develop a nuclear weapon. Iran is aware of our resolve." In turn, British Foreign Secretary Boris Johnson said on the sidelines of his meeting with Israeli Prime Minister Benjamin Netanyahu that the United Kingdom believes alongside France and Germany that Irans nuclear agreement is the best way to ensure future security in the region. “The UK, alongside France and Germany, firmly believes that the Iran nuclear deal is the best way to ensure a safe, secure future for the region,” Johnson said.  “We are committed to making sure Iran continues to abide by its obligations under the deal and are in full agreement with Israel that we must prevent Iran from acquiring nuclear weapons,” he added. Meanwhile, Iran’s Mehr News Agency reported that President Hassan Rouhani is heading to China for the Shanghai Cooperation Organization summit to promote cooperation, but the nuclear deal is expected to headline his agenda.   Tehrans ambassador to the International Atomic Energy Agency Reza Najafi announced Iranian intentions to reactivate the state’s nuclear program in the event of canceling the international agreement signed 2015. Najafi also gave the European parties to the nuclear deal several weeks to salvage the accord. Iran’s declaration that it could increase its uranium enrichment capacity if the deal falls apart risks sailing close to the "red line," France’s foreign minister Jean-Yves Le Drian said on Wednesday. The Europeans are trying to keep the deal.
