A 2017 estimate of Iran's population is 81 million. Its area is 1,648,195 sq km. Iran won't be a pushover like Iraq was before turning into a disaster. It will be a disaster from the get go.
The other nations in the nuclear agreement won't go along with Donny. Bibi Netanyahu will go along with Donny but he isn't part of the JCPOA. So Donny wants the other nations in the JCPOA to follow him down the garden path while he scraps the JCPOA and encourages Bibi to attack Iran.
So the way I see it peace is the baby and the JCPOA is the bathwater. Scrap the JCPOA and peace goes down the drain with it.

I believe that keeping the deal’s constraints on Iran’s nuclear program will also help counter Tehran’s aggressive regional behavior. I am sure of one thing: every available alternative is worse. The wisest course would be to improve the handcuffs rather than break them.
