I think they could not do what they're doing. By definition all resistance groups can't do much against the powers they're fighting but they definitely don't, and haven't unless you're Hamas, do what Hamas do.
Why don't they, because in my opinion most resistance moments are primarily concerned with securing land, peace and sovereignty for their people. Hamas are concerned with global Jewish (And western really) genocide. So it makes perfect sense why they do what they do and why the ANC, who were thinking about life after they won and how they could best win people over and things like that and not just we need to kill all the whites or the Irish saying we need to kill all the Brits and **** our people and anything else.
