Regardless of how wars are won, they are prevented by altering the risk picture for the enemy.
This is also why many smaller NATO states are scrambling to procure long-range missiles outside of US control. In a hybrid war with Russia, they would control the escalation ladder - I.e. be able to yeet some high explosives at powerplants and fuel depots - rather than relying on Washington to grant permission.
Ukraine has been doing similar with the flamingo and other cruise 'missile drone' projects. Iran as well - look at their response to US aggression.
The trajectory is clear, mass precision strike is cheap and corresponding defense is not. Having a stockpile of millions of flying problems for your enemy to consider is the best deterrent short of nuclear weapons.
