Sci-fi series The Expanse has a very interesting scene calculating the game theory between stealth, first strike weapons and a preemptive attack on these weapons given good intel.

The risk is that if the attack is not perfect, it will trigger the use of those first strike weapons.

If the preemptive attack is successful, it will likely lead to an end to the war.

But... what is the probability of success? What would the casualties be in failure?

The dilemma is well acted. It's a great scene. 

It's also unfortunately relevant in the real world today.
