It is not a contest, otherwise, Hamas would win in the terrorism department. Hamas has let it be known from the beginning that their main ambitions is the complete destruction of Israel and to replace it with an Islamic state. That is a declaration of war, a war that they do not intended to abide by the UN Rules of War, therefore they are not subject to protection under these rules.
The periodic removal of Jews from Gaza goes back at least to the Romans in 61 CE, followed much later by the Crusaders, Napoleon, the Ottoman Turks, the British and the contemporary Egyptians, and more recently Jews removed themselves from Gaza in 2005 and it appeased no one. Within a few weeks of every last Jew removing themselves from Gaza, Hamas rockets rained down on Israel. Lesson learned! However, Jews definitely lived in Gaza throughout the centuries, with a stronger presence in the nineteenth and early twentieth centuries. How many live there now?
