"...BUT the little I do know is the pact was the only way..."
So, what happens to your claim when I show that sanctions were killing the Mullahs?
“And so we could still maintain some of our unilateral sanctions, but it would be far less effective -- as it was before we were able to put together these multilateral sanctions.” – President Obama The Facts The most effective sanctions against Iran have been those that give companies and countries a choice to· do business with Iran or the United States. When given such a choice – which would still be possible to if Congress rejects this agreement – they have chosen the United States.
The Obama Administration has never liked sanctions, and fought vigorously to oppose sanctions targeting· Iran’s Central Bank in December 2011. Then – as they are now - the Obama Administration claimed that imposing these sanctions would divide the international coalition, and leave the United States alone in the world. Businesses, and in particular banks, will be hesitate to put a premium on the Iranian market if that would· mean getting shut-out of the United States.
As much as President Obama doesn’t like it, we are still number one in the world. While maintaining a united sanctions front after Congress rejects the nuclear agreement will be difficult,· it will be easier to do so today than five or so years down the line when Iran is caught cheating and a sanctions regime must be reconstituted. There were no signs of the sanctions regime collapsing when the Obama negotiations began"

"When you look at the diplomatic insults and the hatred the Obama administration has poured on Israel and Prime Minister Benjamin Netanyahu, when you look at the pressure this administration has put on Israel to negotiate with people who use terrorism, and when you look at
how openly it has enabled Iran to obtain nuclear weapons and ballistic missiles, ...
".... in ending economic sanctions as part of the [Iran] nuclear deal, the Obama administration just gave over $100 billion to Iran, the top terrorist-sponsoring nation in the world—by far! Iran is famous for sponsoring some of the most violent terrorists on Earth, terrorists who continually attack Jews.
Iran has promised to
wipe Israel off the map.
It supports Islamic terrorists who want to do the same.
And they want to wipe President Obama’s
own nation off the map as well!
They call America the “big Satan” and the Jewish state the “little Satan.”

"North Korea: Iran's Pathway to a Nuclear Weapon
A central plank of the Obama administration’s case for the nuclear deal just concluded by the P5+1 powers is that the agreement closes off "all pathways” by which the Iranian regime could acquire a nuclear capability, at least for the coming decade.
That, however, simply isn’t true. The Joint Comprehensive Plan of Action (JCPOA), as the new nuclear bargain is officially called, only addresses the overt means by which Iran might go nuclear. A covert path to the bomb, entailing the procurement of materiel from foreign suppliers, still remains open to Iran, if it chooses to take that route.
....over the past three decades,
Iran and the Stalinist regime of the Kim dynasty in North Korea have erected a formidable alliance—the centerpiece of which is cooperation on nuclear and ballistic-missile capabilities." North Korea: Iran's Pathway to a Nuclear Weapon
