Completely different, Israel is a nuclear power surrounded by enemies who only possess conventional weapons, if Israel didn't have nukes they would have been invaded decades ago however they do so nobody attacks them due to fear of annihilation.
The UK on the other hand is a nuclear power with enemies that are both nuclear and non-nuclear. It requires subs to ensure an enemy cannot simply nuke us and then get away with it because we're a wasteland, they know our subs would annihilate their country so would never risk a sneak attack.
If this country had never developed nuclear weapons they you and I would either not be here or would be speaking Russian lol.
