I'm sorry but that article has nothing to do with the topic at hand. Every country on earth executes informants.
On paper, that's "collaborating" with Isreal leading to execution (GP: "they'd risk execution for "collaboration" if they did this").
I suspect that there was a (horrible) case like this that was promoted within Israel to drive the sort of talk that I was responding to. An incident is taken out of context, rebranded and sold as normal behaviour by a demon state.
I'd like to see the articles about people in Gaza being killed for getting support from people in Israel.
