I remember reading about digital warfare and how the character of different weaponry can be stabilising or destabilising.

So the example given was nuclear weapons. The consequences of using them are so disastrous that there is no good use case, and so they tend to be stabilising. They discourage use.

Digital warfare is destabilising, because it's very easy to do and very hard to catch, so you're better off using it, even without any declared war.

Information warfare is probably very similar, it encourages use, but that's because it's very low-stakes. It wouldn't be very exciting. I imagine it'd make a better comedy than a drama.
