Just refer to Obama's comments that echo your sentiments about Iran and its behaviors.
After that, you expect them to cozy up to America publicly? Without which this deal is a failure?
The point of the deal was to cut their pathway to a nuclear weapon. It was not to transform them instantly into a close ally, a subservient puppet state, or to effect a regime capitulation. None of those were options remotely on the table, and it's usually the case in diplomacy. Negotiation is not bulldozing the opponent into submission. It's getting a deal that both sides can accept.
I think you are missing the point. Iran has not had a history of being open and honest when it comes to weapons inspections, whether its through the US or UN. They have openly lead chants "Death to America" as well as the desire to eradicate Israel. Unless they have new leadership through fair elections, its complete naive to expect that their behaviors and intent will change. If Iran truly desires to be more accepted by the US and throughout the world, it will have to show more willingness to condemn Muslin extremists and terrorists both within Iran and in the region. They will understand that America is NOT a bad country who intends to do harm to others for no reason. For a century the US has used its resources to help promote peace throughout the world and make it a safer place. If Iran wanted to show goodwill, it would have released 4 prisoners it still holds as part of this deal, and the Obama administration should have made this part of the deal. That was a big mistake.
Do you view Iran as an ally or an enemy? Do you think its plausible that they will change their behaviors and actions and truly become a long-term strategic partner in the Middle East similar to Jordan?
In other words, whatever Iran agrees to, they need to do more, i.e. the infinite moving goalpost?
Another nation on this planet with any nuclear capacity scares me, but the doomsday scenario of Iran sneaking to a quick breakout is no worse than North Korea and Pakistan having nuclear weapons. India and Israel are also non-signers of the NNPT and technically in position of arsenals that violate international law. Pretty sure there's plenty to be scared about with signers being shockingly careless with weapons at times too.
One thing I think about frequently is that less than ten years after 400,000 Americans died fighting in WWII, (West) Germany and Italy had joined NATO, and Japan also signed a mutual defense treaty. In the last 40 years Iran took over our embassy and embarrassed a President out of office, probably helped with the Beirut bombings, and probably provided shaped charges for IEDs to Shiite militias in the previous decade. We shot down one of their airliners. We probably provided some assistance to Iraq during their brutal war with Iran.
Not to brush all that off as irrelevant, but I think if we could get over the terrible things Germany and Japan did throwing the entire world into the bloodiest conflict in history, we can probably get over the rocky past with Iran. Iran is the only country between Israel and India that has a diversified economy, educated middle class, and some semblance of stable, functioning democratic institutions. Human rights are awful by western standards, but quite liberal compared to their neighbors, and would likely improve with better relations. I don't think it's entirely unrealistic to think that Iran could be persuaded to abandon their nuclear program for the same reason the apartheid South African government eventually did, and maybe in the longer term, the theocracy will fade to a more vestigial role with stronger democratic institutions.
At any rate, a military strike on Iran would be a catastrophe that wouldn't degrade their nuclear capability, and there's a point where sanctions only drive a nation down the path of completely rogue pariah state (see: North Korea, has nuclear weapons). I guess if taking a chance at this crossroads backfires, then Obama's successor can look forward to total dysfunction stretching from Syria to Pakistan with no solutions. If it works, there may be somewhat better options in Iran, Iraq, and Syria, at least pertaining to the destruction of ISIS, and a return to a modicum of stability.
