Here are the key elements of the Iran Nuclear deal. Trump and the cons will not give them any publicity, because, according to all our allies and the experts, they have been effective, and undercuts Trump's claim that "it is a disaster".

1) international economic sanctions imposed on Iran would be lifted, allowing Iran to regain frozen assets of about $100 Billion and to resume selling petroleum on the world market
2) Iran will limit use of its centrifuges, with about 20,000 removed, allowed to use only oldest and least efficient 5,060, which are incapable of producing weapons-grade uranium...for 15 years
3) Iran will reduce its uranium stockpile by 98% (it transferred about 90% to Russia). Iran will not have any weapon-grade uranium, enriched to 90%. It may keep only 3.67% enriched uranium, for 15 years
4) Iran will re-design its newest nuclear reactor at Arak, so that it will not produce heavy water containing weapons-grade plutonium, for 15 years
5) Verification. International Atomic Energy Agency inspections are allowed access anywhere in Iran for 15 years, and Iran will have 24 days to comply with any request.
The removal of Iran's stockpile of weapons-grade enriched uranium and the centifuges necessary to produce it pushes the amount of time to produce enough plutonium to create a bomb to more than one year, well beyond the 24 day compliance standard.
