No they didn’t. See sources in replies. Hamas’ attack at the music festival was awful, bar none. But that doesn’t mean you should blindly believe IDF war propaganda being used to further oppress and disenfranchise the Palestinian people.
There’s literally a genocide going on against them. They live in an apartheid state where they have essentially no rights. Hamas doing bad stuff does not mean that state funded genocide campaigns against Palestinians are OK. The propaganda is meant to legitimize the violence against civilians.
