Why is Israel getting away with these atrocities?

Wikipedia writes:Hamas regards the territory of the present-day State of Israel ” as well as the Gaza Strip and the West Bank ” as an inalienable Islamic waqf or religious bequest, which can never be surrendered to non-Muslims. It asserts that struggle (jihad) to regain control of the land from Israel is the religious duty of every Muslim (fard `ain). This position is more radical than that now held by the Palestine Liberation Organization (PLO), which in 1988 recognized Israel's sovereignty. Hamas does not recognize Israel as a sovereign state and refers to it as the "Zionist entity", a common hostile term in Arab political rhetoric, and calls for an end to the state of Israel in its charter.
