Ya know that for sure? I don't mean some lithium chemistry. The simpler solution is obviously to use a traditional chemistry. I've been speculating recently that it is likely possible to make a single use battery from an explosive. A battery is just exploiting oxidation like reactions with the galvanic potential of metals. Explosives are basically unstable stuff with lots of potential combined with a rapid oxidiser. The two uses have quite a lot in common. I bet there is a bunch of untapped potential in this space where little research is done in the public sphere.
There's emerging evidence that it wasn't explosives and might have been the battery. And there's certainly been reports of exploding batteries injuring people to similar degrees.
Regardless I think this is going to effect western made electronics sales and be an attack methodology that's leaked and used against Americans forcing them to actually pay attention to Israel.
I'd guess biological, but they already trashed the clean water so we crossed that bridge. Ovens. Ovens are the next logical step for psychopaths like the extremist Israeli government.
