Every now and then, almost yearly now, the conspiracy theory scene pings one of my favourite theories: the Russkies have the electromagnetic spectrum well and truly under their grasp, and can disable any other military simply by flicking the off switch. They've discovered some way to do this, and it works every time.

Its a far-fetched and bizarre concept, and surely there are detractors and supporters of the theory - but for the sake of a thought experiment, imagine it were the case.

Would you use this capability, much?

Or, would you use it sparingly, in such a way as to avoid detection - say, introducing the odd power-cycle glitch here, maybe a spike there - just enough to keep your target occupied, but not enough that they'd wise up to so much sabotage.

I mean, you wouldn't just fly over a US destroyer/carrier fleet, and demonstrate it, overtly, naturally...

Would it instead be better for people to believe such capabilities are impossible - and if this is the case, how do we prevent a hundred years of Tesla's and Theremins' from stumbling onto the technique again, hmm...
