You don't seem to get it. The object of the exercise is not nuclear yield. BTW, you can physically damage fissile material that needs to be in a particular physical configuration with neutrons and/or x-rays. One is not trying to detonate the weapon, but rather render it in a state where it cannot reach the desired yield (preferably none at all, of course).
