In large scale modern warfare better weapons have generally won the day and no serious military professional in their right mind is going to say...hey, give me some of that low-tech stuff please.

Probably true, but not right. The Viet Cong defeated a far superior force with tunnels, bamboo shoots in pits, and a paltry few munitions. Biplanes with wings of fabric sunk monstrous battleships in World War I, (I am reminded that Kamikaze’s did the same in World War II with outdated airplanes), and there is a story that the Romans defeated somebody or other (not Hannibal) who came charging in on war elephants simply by arranging their soldiers in smaller platoons instead of a great massed line so they could simply “step out of the way” when the elephants rampaged. They also blew trumpets to scare the elephants which made them useless for whatever the other country was. (I forget the details, but have always been a fan of the “little guy” tactics that can sometimes prevail.

I imagine Ukraine would trade weapons with Israel in a nano-second

Yeah, that mystery nuke in the basement would make a big difference.
