France, Britain, and Germany are playing with fire. Iran will walk away from all deals if pushed. They haven't wanted, and still don't want, nuclear weapons; but, if pushed, they'll develop a whole new class of conventional weapons with Russia and China and others that will be just as effective, just not planet poisoning.
Federica Mogherini is the only one who shows any sense and integrity here. She's the only one I trust in that European group on this issue. She does make mistakes, however.
