Israel/Palestine

next president, and his threats regarding dismantling the deal have enough experts concerned about it

It shouldn't surprise anyone if they ratchet up some lame excuse for a purported violation by Iran as an excuse for the U.S. to leave.

Recall the bush administration unilaterally walked away from the ABM treaty

Even if they don't formally leave, they can, and most like will apply economic and other sanctions against Iran, thinking it would give them leverage.

Again, there are enough concerned voices out there that a trump administration could dismantle the deal unilaterally.

" Dismantling the deal is very possible, but it's not simple either.

Trump won't be able to simply throw is hands up and walk away. He would have to work with Congress to enact measures to undermine it, such as reimposing U.S.-based sanctions that were lifted. He could, for example, recreate the sanctions that prevented U.S. aviation businesses from selling to Iran and in turn scuttle the Boeing deal. That would anger the Iranians and could cause them walk away from the nuclear terms; and it would also likely upset Boeing.

Or he could take a strict enforcement approach to the current plan and attempt to end the deal if Iran falters in the slightest and fails to meet its own obligations. Outside observers opposed to the deal argued last week that Iran has already violated the terms of the deal by exceeding the producing limit of heavy water at its Arak nuclear facility. The U.S. has sought to downplay the incident, saying the Iranians acknowledged the excess and made no attempt to hide it, but a Trump administration could just have easily argued it was a violation.

Any such complaint of a violation would be sent to a "dispute resolution mechanism" as outlined in the agreement, but if that governing body is unable to resolve the issue, the complaining participant would then have the right to end its commitments to the deal."
