I don’t know why they’d drop a bomb on this place, be a heck of a waste of a bomb.

Our reading
An editorial interpretation.
The speaker dismisses the place as an unworthy target, joking that bombing it would waste the bomb. That calculation makes destruction sound like a question of value for money. The humour comes from using the imagined attack to express a very low opinion of the location.
