Let me articulate the thing which I believe is on many people's minds:

What is the chance the president will order a nuclear strike on Iran as this war proceeds?

We would hope the odds are vanishingly small, because doing so would be profoundly disadvantageous. But the same was true for initiating this war in the first place. The logic -- such as it is -- of some people in power may lead them to conclude once more that shock and awe can succeed. We've already struck the country with powerful conventional weapons at scale and it has not led to a weakening of Iranian resolve.

All the above said, my personal hope of course is this will never happen. I'm curious what other folks think however.

No chance. A nuclear strike on Iran won't achieve anything that a large number of conventional strikes would.
