Actually, it shows your profound ignorance of what went on in that deal. The negotiations began with Germany, France, and the UK seeking to circumvent sanctions to secure that sweet, sweet Iranian oil. So they hammered out an agreement that would mollify both the US and Iran. We'd get inspections, they'd get sanctions lifted, and eventually, the return of assets we had been ILLEGALLY holding since the 1970s. Eventually, Russia and China were brought in as well.
So it was actually a pretty good deal, which Trump tore up, because the Jews wanted it torn up. And of course, because Trump wanted to undo anything with Obama's name on it because Obama made fun of him at a dinner once. (Yes, he is that petty.)
Iran came to Geneva in good faith and was willing to not only return to inspections and stop enrichment for even peaceful purposes. Not good enough for the Jews, of course. They launched an attack, and Trump went along with it. Now they are stuck because they can't commit ground troops, and there's really only so much you can accomplish with airstrikes.
They aren't afraid of Iranian Nukes. They are afraid that Muslims will throw out corrupt dictators and kings. They aren't afraid the Iranians might get the cutting-edge weapon of 1945; they are terrified that other countries might look at Iran and say, "Um, yeah, an Islamic Republic actually does sound a lot better than some Rich King who flies to Europe on Weekends to screw White Hookers."
