Explosives are routinely destroyed in controlled explosions, controlled detonations allow for us to choose when and where the ordnance detonates, minimizing collateral damage. Towing it is too dangerous when you don't know when it will detonate (imagine it detonating in port, even at sea it could kill the ship crew), and allowing it to just sit at sea leaves it at risk for detonating in the vicinity of an unsuspecting vessel.
