What are your thoughts on the deal?
For stability of the region, commerce, peace and moderate forces in all parties, it was a good deal.
It wouldn't have resolved all the issues the world has with Iran, but the idea of having a "deal" in place that resolves all issues is childish.
Eg can the US have a "deal" with Saudi in place to resolve all the regional and human rights issues with them? Of course not. But those who argue against the JCPOA claim the US could've had a "deal" with Iran that resolved all issues.
It would've been used to rebuild some trust between both nations and help resolving other issues in long term.
Although right now the deal is hanging by a thread, I still think its possible that in long term it will be considered a major victory for all parties involved.
The fact that the hardliners couldn't kill it off despite years of effort (while being in power) may be later judged as a strength of it.
