The sentence in bold is coherent even if the “power” he refers to are capabilities less “powerful” than a nuclear weapon.
Exactly - it probably references a different TYPE of power. Lasers perhaps. Computer viruses to disrupt weapon systems, the power grid, communications, etc. Perhaps a local EMP weapon to shut down all electrical systems. I’m guessing and hoping that it isn’t a chemical, virus or similar weapon. Plus - Iran already knows about that “power” from their own use of it.
