(Of course some Israel politicians are religious; that's true of any country.)
If it looks like a duck, quacks like a duck, and does what a duck does, it is a duck.
There is "religion" in the broader sense which can be any set of beliefs but Netanyahu is as secular and logical as can be. He may be overly logical in the sense of advancing his personal agenda (avoiding standing trial) over the interests of his country but he's still very different than the religious crazies in Tehran where logic plays no role and g-d is everything.

The region will have chance at peace once the regime of Iran is removed.
If Iran's regime had nukes, I guarantee you'll see UAE, Saudi Arabia, Qatar and several others go all in on their own nuclear programs immediately. They'd be fools not to.
Israel's nukes are troubling, but the weird "nuclear ambiguity" doctrine has already stood for so long and managed to avoid nuclear flare-ups so far. I'd still like them to not have nukes, but they won't be launching any nuclear first strikes for sure - since we've seen them not do that even while fighting many major wars and suffering losses without taking that step...
