The Jewish Press:
"ObamaDeal” explicitly states that the United States and the other P5+1 powers can help Iran deflect and even “respond” to sabotage and nuclear threats to its nuclear sites. The damming evidence that ObamaDeal directly allows Western powers to help Iran to protect its nuclear sites, and possibly even to stage a counter-attack on the source of the threat, is stated in Annex III of the Joint Comprehensive Plan of Action (JCPOA). Congress is reviewing the agreement and has the option to cancel America’s commitments under the deal.
You have to reach page 142 of the JCPOA until you reach “Annex III: Civil Nuclear Cooperation,” where Section “D 10 states that the P5+1 “and possibly other states are prepared to cooperate with Iran on the implementation of nuclear security guidelines and best practices. Cooperation in the following areas can be envisaged:
Co-operation in the form of training courses and workshops to strengthen Iran’s ability to prevent, protect and respond to nuclear security threats to nuclear facilities and systems as well as to enable effective and sustainable nuclear security and physical protection systems [boldface added];Emphasis should be placed on the word “respond.” It leaves open for interpretation the possibility that the United States and other P5 +1 countries can take action in the form of training and preparing Iran to stage a cyber attack or retaliation in the event of a third-party assault on Iran’s nuclear facilities.
Co-operation through training and workshops to strengthen Iran’s ability to protect against, and respond to nuclear security threats, including sabotage, as well as to enable effective and sustainable nuclear security and physical protection systems.
There is a lot open for interpretation here. However, it does look like the U.S. has agreed to protect Iran from an attack by a "third party." Israel and Saudi Arabia are the two nations mostly likely to attack Iran's nuclear sites. While that does not necessarily mean the U.S. will go to war with its allies, it can happen.
