And yet they upheld their end, over and over again.
So how does this improve the situation? How does this improve the probability of preventing Iran from attaining a nuclear weapon? What is the endgame here and why is this going to achieve it?
I've asked this question to you right-wingers for years and never gotten an answer.
I simply think the JCPOA is too lax, it's not strict enough on Iran.
Lifting the U.N. sanctions on Iran's ballistic missile program as a concession to get them to enter in to the JCPOA was just unwise. A country's nuclear program is divided in to three main parts, development, weaponization, and delivery. Ballistic missiles would fall firmly under the delivery category. Arguing that the JCPOA has stopped Iran from developing nuclear weapons, as they continue to launch and test ballistic missiles which are an integral part to nuclear payload delivery, is just untrue. According to the FDD, Iran has conducted at least 23 ballistic missile tests since the JCPOA was ratified. It's unacceptable.
My personal biggest problem with the JCPOA comes from the "sunset" clause. Iran's nuclear restrictions should not have an expiration date. Iran claims that they will abide by the Nuclear Nonproliferation Treaty after the restrictions expire. If anyone believed that BULLSHIT there would be no reason to need the JCPOA in the first place.
And for the record, Iran has violated the JCPOA on multiple occasions, which highlights another inadequacy with the JCPOA. There are no agreed upon consequences for Iran violating the term of the deal. The looming prospect is to reimpose all UN sanctions on Iran, which is the equivalent of the death penalty. When the death penalty is your only option as a punishment, violations go unpunished. There was no punishment when Iran on multiple occasions has been found to have more heavy water (a form of water used in nuclear reactors) than permitted by the deal. There was no punishment when according the FDD Tehran has found and are using new ways to conduct mechanical testing of nuclear centrifuges, a clear violation of the JCPOA.
