the P5+1 agreed to a six-month interim deal that involves the freezing of key parts of the Iranian nuclear program in exchange for a decrease in sanctions, to provide time to negotiate a permanent agreement. Iran will stop enriching uranium beyond five percent, and will stop development of their Arak plant. The UN will be granted greater access for inspections. In exchange, Iran will receive relief from sanctions of approximately US$7 billion (£4.3 billion) and no additional sanctions will be imposed. President Obama called the agreement an "important first step."

In 2018 the Mossad reportedly stole nuclear secrets from a secure warehouse in Iran. According to reports, the agents came in a truck semitrailer at midnight, cut into dozens of safes with "high intensity torches", and carted out "50,000 pages and 163 compact discs of memos, videos and plans" before leaving in time to make their escape when the guards came for the morning shift at 7 am. According to a US intelligence official, an "enormous" Iranian "dragnet operation" was unsuccessful in recovering the documents, which escaped through Azerbaijan.
