It’s true Palestinian Americans will rarely get reported on due to media bias, but they’ll still report on incidence like these effecting international aid workers and journalists as they sympathize with them more, even the above article mentions 196 have been killed and that’s from months ago.
As for the state non-state definition the u.s. has gotten around that with calling them “state sponsors of terrorism” putting them on a list and imposing sanctions. The fact Cuba is on that list and Israel isn’t really shows the legitimacy of it.
