My take:
- Iran signed an NPT [a non-proliferation treaty] long ago (see this), albeit under the Shah.
- Iran breaches NPT
- US and the west try to negotiate something to be able to enforce the original NPT.
- US and the west agree to weakened conditions of original NPT.
- and the US and the West believe Iran will honour the new agreement.
Jack's assessment:
Compliance failure is hard wired into the agreement, according to this account:
A deal has been reached between the world powers and Iran over the latter’s nuclear program after a series of major American concessions, Ehud Yaari, the Middle East affairs commentator for Israel’s Channel 2 television, said Friday night. “It is done. It is done,” he said, and will be signed “early next week.”
The aim of the agreement is to put a negotiated end to a 13-year standoff with Iran over its suspect nuclear program and to block its pathway to developing a nuclear bomb in exchange for lifting biting global sanctions. Israel’s leadership has relentlessly opposed the emerging agreement, with Prime Minister Benjamin Netanyahu warning that it will pave Iran’s path to a nuclear arsenal.
