the JCPOA treaty was appeasment suck in many ways . All the signatories deliberately choose to ignore the blatant Iranian lies ;to leave off the table Iran’s development of ballistic missiles ;and Teheran’s involvement in terrorism and international criminal activity. It was all carrot and no stick.
It actually forbade punishing Iran for violations of the deal except if Iran cancelled the deal. Trump's apparent goal is to address the obvious flaws of the deal . Me ;I don't believe the regime will ever be honest brokers because there is nothing to compel them to short of war. The other idiot signatories are only concerned with the energy the Iranians can provide.So they are desperately attempting to help Tehran circumvent the sanctions . But in doing so they show themselves to be the feckless players they are …...which further emboldens the 12ers.... and demonstrates to the world how un-credible and unreliable they are as partners .
This brinksmanship Iran is engaging in is predictable and they will continue to escalate until there is an effective response . And that won't happen until the so called partners get their heads out of their posteriors and realize their timid response almost guarantees the Tehran will breach the nuclear threshold and become another rogue nation with nukes .
