It’s quite easy for people who know what they’re doing to repurpose processors and components in consumer devices? And, you can also buy almost whatever cpu/component you want on Amazon too if you know what you’re looking for?
Otherwise, as I mentioned I don’t like it as a category because it leads to this silliness. At one point Israel was blocking all concrete imports to Gaza under dual use reasoning, and although I don’t like them one bit they kind of had a point. But, you also kinda need it if you want to build modern structures.
I’d assume NATO’s largely talking about machining equipment, electronics, and drones though. But, I don’t think they actually clarified anything? And while Ukraine itself probably doesn’t have much military use for the first two as any military plant would probably get hit, with how prominently drones have featured in this war they definitely fall under dual use.
