> They mention the large chunk of high explosive in there, but the key attribute of high explosives - by definition - is how hard they are to actually trigger.
I think the term you might mean is "secondary explosive"? Because as stated this is _very_ wrong. Nitroglycerine is a high explosive. Nitrogen triiodide is a high explosive. Not really compounds known for being hard to trigger, unless you consider a light featherdusting to be rough treatment.
Otherwise I suspect you have a good point, just the terminology seems wrong to me.
Yes, I am wrong it seems. I am unsure where I got the high<->secondary mixup from, I'm sure I saw something talking about high explosive and defining it strictly as "needs supersonic shock wave to initiate", but have just checked and can't find anything saying that. Will edit my prior comment, thanks
I'm far from an expert (I just like fun parts of youtube xD) but I'm wondering if the terms just get conflated because the only high explosives anyone will use a large amount of by choice are the stable ones, so they're (almost?) all secondaries too.
