I don't think this is solid reasoning. The amount of energy in a system may well dwarf a given input, but that doesn't mean that the system doesn't have multiple equilibria that a sufficiently large delta could shift it to. For example, the energy to fly a plane into the sky is small compared to what's released in a rainfull, but that doesn't prevent cloud seeding from being (somewhat) effective. The energy from a lit piece of magnesium is much smaller than what results from touching it to a thermite block. It is of course the responsibility of the pro-nuke-on-hurricane folks (do they even exist?) to offer the mechanism that a nuke uses to shift the hurricane system to a lower energy state in a controlled manner.
