You have some mischaracterization in your framing of this discussion.
In general, the deal was **** for the US. It addressed nothing and didn’t provide access to what was really needed nor did it address some of the other touchy issues.
You are seeing push back from Germany, UK, and France because they are getting heavily invested in trade deals with Iran. They aren’t pushing back because they think this will actually work to the ends it was theorized. Iran is still exporting terror in the region. I was in Khamis-Mushat, SA back in the fall when the Saudis intercepted inbound missiles from Yemen which Iran was responsible for. So that’s first hand experience. I have teams all over the region. Killing this deal doesn’t make our EU allies happy, but it does strengthen our relationships in the region with Saudi, Jordan, Iraq, Qatar, UAE, Lebanon, Kuwait, and Israel. Basically all of the countries that were pissed off because of the previous deal. These countries are actively engaged in suppressing radical Islam within their borders.
This deal was akin to the Munich Agreement of 38. It was horrible. With Iran, nothing short of Regime change will solve the problem. This can be done without a formal shooting war. We’re actively working towards those ends now. At this point, there is a trifold strategy with Iran that all ends with its collapse. Make no mistake, we’re actively fighting Iran all over the region. Moreover, this should have been served up to Congress to debate and decide at the onset. It wasn’t.
Will we work a new deal? Doubtful. If we do, it will be because Iran asks for it. Otherwise, we’ll sit and let the country collapse internally.
