No, it's just been so isolated that only Israel can control who and what goes in and out, to the point NGOs have described it for decades as the world's biggest open air concentration camp. I don't condone the horrible things Hamas did (that were actually proven and not later disproven hasbara, like the rapes), but I'm also not arrogant enough to tell an occupied people how they should be resisting their occupiers, especially when the target is a military outpost (which is essentially what the kibbutz was) mere miles from Gaza and being used as a base largely by standing members of the IDF and their families (i.e. the occupying force). Desperate people take desperate measures, who knew? The Irgun and Haganah probably should have thought about that before they violently persuaded the British into giving them a "homeland" that already had a people - including Jews and Christians - living in relative peace on it for almost a thousand years.
