The international community has been nurturing the dysfunctional status quo for some time in hopes of a two-state solution. With one hand providing weaponry to Israel–usually but not always defensive equipment like AA–and with the other billions in humanitarian aid to Gaza and the West Bank. Meanwhile other foreign actors have been funding the insurgency in Gaza to disrupt peace efforts. It's a very messy situation where the state of Israel has both committed crimes against Palestinians and is simultaneously presently unable to just go hands-off as foreign actors have demanded.
One needn’t even go as far as “the international community”, Hamas was funded by Israel itself as a perceived counterweight to the secular PLO. Divide and conquer is what kept the Israeli settlers moving outwards, and that necessitated funding and supporting the Muslim Brotherhood and later Hamas.
