The sole craftmanship of the entire plan is the US. They have their own weapons, but the ones made known and the ones unknown to us. Germany China, the European countries have their own weapons which I believe every great nation should have a strong defense weapon. But the US are scared, why Iran had been developing the nuclear weapons.
It is not obvious to me that there are countries who don't want others to leave in peace. It can't be possible for one nation to rule the world, if that is what Trump has come to do then he is going to fail.
They don't call them the world power for nothing you know.
Without Nukes, the Iranians are holding up their defense pretty well and even fighting back, so imagine if they've got some of those in their Arsenal. The thing about these Nukes is that, you just might not know how much damage those things can inflict. And that's exactly what the US is trying to avoid, using Israel as a camouflage to do their thing and still appear to be appear to be ones proposing peace.
I see that the US isn't really interested in hurting nobody in Iran, thus their reason for proposing a peace talk, if Iran was so interested in putting an end to all the killings and attacks, then they'll just accept the treaty and then maybe come to reasonable terms with the US and all these would end in no time.
It would be tough for Israel or the US to achieve their aim without a war cause Iran won't back down on their project they've been on it for years and spent billions to try be among the nuclear war head so Trump can't dictate for them concerning that, not at this point, and not forcefully, I know they're scared that Iran might use it against their neighbors (Israel) if they succeed in producing more nukes, maybe for a retaliation for killing the Hezbollah and Hamas generals, and making several Palestinians homeless, but destroying Iran's facilities, killing scientists, and those generals wasn't a good way to go about it cause the result was a retaliation by Iran and further destruction from both parties. What the world need is peace wars causes death and destruction and the innocent people suffer the most while war mongers would still continue to live afterwards.
