You are lumping together three very different countries into a western mindset of deterrence.

While Pakistan is Muslim they are not the same as Iran in any way. The current rulers of Iran do not operate by western logic and would be consider a "holy death" as a direct path to heaven.

Iranian populace isn't behind that, the people themselves are reasonably secular and aren't behind that. However, the leadership is dangerous and you should not assume they would use western logic.
