“Germany and the other parties to the agreement will likely ignore our decertification and refuse to support new sanctions on Iran.”
And they will instantly become a nation violating the sanctions and will face serious restrictions on selling in the USA. And there is a President sitting there now who will roast their feet in the financial fire.
