If you are against any use of force which could have collateral damage, then you are effectively against any use of force. That's a principled stand, but not actually very realistic.
Fortunately weaponized lasers are coming. Those should succeed in reducing collateral damage almost entirely. All that needs fixing after that is the often-faulty intelligence, and weeding out gung-ho idiot drone operators.
(Very Very hypothetically) Russia annexes half of western Europe and starts massing troops on the border and deploying landing craft then you can open fire.
It's not very realistic purely because of the way the world currently works, as Von Clausewitz said "War is the continuation of diplomacy by other means" and it shouldn't be.
If that is true, then it's not "could have", it's "almost definitely will".
