I mean there's a very clear difference between 'strategic tech' that's supported by defence (GPS) - and weapons systems (Spitfire).
And yes, some weapons systems are just ... 'weapons related' ... and the dual-use comes later, so it's more nuanced. Some of it more obvious (radar), than others (cruise missiles).
But I think it's important to characterize these things.
Why is it important? Do those arbitrary labels allow us to feel morally superior to those who make different choices?
