So they discovered a site that has since been destroyed. Should we carpet bomb the destroyed site?
Nice sidestep.
What they discovered was a nuclear site that should not have existed if they were abiding by the nuclear deal they signed. IOW, they were cheating before we pulled out. That speaks to the deal not being worth the paper it was written on.
We had a deal with North Korea too. Look how that turned out. If Iran wants nuclear weapons, it will have them eventually.
Was your point that we should not have bothered with the Iran deal then?
Obama's Iran deal was the biggest clusterfuck of his entire presidency. Even Ali-Akbar Saleh, the man who heads the Iran Atomic Energy Agency said “Iran’s nuclear program remains intact, we have done nothing that could not be undone with the turn of a screw.”
Then Iran went on to test a new generation of missiles which because of their long range and small payload, it was evident that they were designed to carry nuclear warheads.
In exchange for some vague promises Iran made, Obama solved the Islamic Republic’s cash-flow problem by releasing unknown quantities of frozen assets. A large number of those assets were in the form of hard cash flown to Tehran via Beirut in sealed safes, all in secret mind you. Part of the cash was $400 million for the release of four hostages held by the mullahs, which was in direct violation of the US policy not to pay ransom. The shithead Iranians wasted no time seizing six new American hostages, immediately after.
A lump sum of $1.7 billion from assets frozen under President Jimmy Carter went straight into the coffers of the Islamic Revolutionary Guard to help it upgrade its adventures in Lebanon, Syria and Yemen. With some of that money they received from Obama, Tehran signed a series of contracts to buy more weapons from Russia.
Even with those clandestine side deals going on, the Obama administration negotiated an agreement without a guarantee that Iran wouldn't eventually build a nuclear bomb. Iran continued to make progress on their centrifuges beyond what was allowed under the nuclear deal, in part through a so-called "quality assurance" loophole that Iran was exploiting to test those centrifuges.
In other words, Obama's nuclear deal explicitly allowed the Iranians to continue research and development activities on highly advanced centrifuges over the course of its duration, while they boasted about the progress being made. Which is why they are even more of a threat today. Obama's Iran nuclear deal didn't put a stop to their quest for a nuclear weapon, it only temporarily slowed it down.
