I looked into it a bit (another commenter called it "not that complicated" which is not a phrase I usually hear in relation to Israeli/Palestinian politics!) and it's pretty interesting: https://www.timesofisrael.com/the-curious-tale-of-israels-sh... https://en.wikipedia.org/wiki/Israel%E2%80%93North_Korea_rel...

Apparently at times some in Israel worked to establish relations with NK, in hopes of improving economic ties & bringing them in the fold I guess, but their efforts were thwarted by others in Israel (intelligence services) and pressure from the USA. And eventually (according to the article) it became clear that "stop selling our enemies weapons to use on us & in return we'll invest and establish ties" was a non-starter, so they gave up.

Also in an interesting reversal of tropes common in US politics, it sounds like the Isaeli government felt they were being unfairly controlled by the US, by being prevented from trying to establish friendly relations with a country the US considered off limits.

It's interesting to think of the counterfactual where Israel invested in NK, NK stopped participating in or arming attacks on Israel, and who knows what else would have happened. Oh well!
