No. These points above may or may not hold ground, it does not matter, what matters is what they acchieve:
self-paralysis.
When I mean you not well and have proven that since years and decades, and I hold a pistol in my hand, and start raising the arm to point it at you, and you do not make me stop that movement before I completed it, then you are - sorry, stupid. Not rational, not moral, not reasonable, not moderate, but simply stupid.
And the risk goes beyond war. It includes the risk of proliferating bomb-capable nuclear material to Islamic terror groups.
The West shies away form the unwelcomed conclusion since twenty years. Europe has given up on keeping Iran form beign nuclear armed, and did so long time ago already. But what is about America, Israel, the Arabs? Turkey?
Nothing but troubles with nuclear Iran. Nothing but steeply risen risks and dangers. Heck, I would prefer a nuclear armed Iraq to a nuclear Iran.
