Trump didn't negotiate that Iran allow for resuming nuclear inspections and halting enrichment even though Iran's resumed nuclear program (after Trump pulled the US out of the existing nuclear treaty) was supposedly the reason for starting the bombing. And, now Trump supposedly wants to seize Iran's nuclear material after the bombing even though they were negotiating to hand it all over right before the US started bombing. Wouldn't allowing them to give it to us have been easier and less costly than bombing them and then invading to take it?
Also, they were now going to charge ships for transit through the Gulf which they weren't doing before the bombing. That will raise long term business costs for every nation that relied on Gulf shipping. NATO nations were going to be paying that cost as well on top of the cost of their military participation.
The treaty was a lose lose for the US and a win win for Iran.
And, as always, it was deliberately destroyed by Israel.
Also, I know what I proposed was harsh towards the US and Israel, but you always have to expect to ease up on some demands in a negotiation. That's why you start out asking for more than you think you will get on your key demands. I think our former allies and trade partners are aware of this.
And, NATO has nothing to benefit by having NATO troops and ships destroyed in the Gulf, but Russia does. So, to see what Russia's ally Iran will actually be willing to give and take to get NATO ships and troops in the Gulf where they can't respond to further Russian incursion in Europe or Chinese incursion in Taiwan, it's a good starting point. Even if NATO eventually doesn't commit any troops or ships.
Israel doesn't care about Ukraine, Romania, or Taiwan. Why should NATO get committed in the Gulf for Israel who will probably violate any treaty no matter what. So, make Israel pay up front and commit to penalties for violating a treaty. And, NATO should only commit to monitoring and verifying safe shipping transit through the strait and to negotiating a cessation of any new violence that might erupt along with securing the rescue of any personnel on affected shipping along with documenting violations of the treaty and any violations of the law of land warfare for potential referral to the International Criminal Court.
