Casually? Are you kidding?
There’s nothing casual about it:
There is NO question Israel would use nukes if pressed hard enough.
I’m not tech minded but they probably couldn’t deliver the nukes anyway. It’s just a deterrent that will never, ever be used!
Wars are fought conventionally. I gave you an example in the other thread of the UK vs. Argentina. If FR existed in ‘82 would you be screaming for the UK to nuke the Argies?
As it happened, the Argies were defeated/humiliated and surrendered
