I’m doubtful that this would solve anything, because for example in the case of Israel, the explosives went through multiple independent security theatres, and the PETN still successfully arrived at the victims. Like, if it happens once, okay, maybe it’s a fluke, but if it happens multiple times throughout the supply chain and every single time it’s A-okay, that’s a problem. Israel heavily relied on regular commercial transport for their bombs. There were countless instances where they could have been stopped, but they weren’t. And that is a worrying signal.

And even if all explosives would be detected with perfect accuracy, from now on, it still would be vulnerable to other points of attack. Just pay off a throwaway goon squad, let them smuggle ceramic weapons in their trousers into an aeroplane, and there you go. And I do believe Mossad and the FSB can come up with better ideas than that. IMO, there needs to be a more effective alternative, than this security theater nonsense.

Edit: And the reason why I’m against it is not only because it has been disproven so many times that it’s impossible to enumerate. It’s also the principle of “guilty until proven innocent”, that is slowly but surely infesting our society.
