How exactly is this about oil? Gaza is not sitting atop oil deposits and all the natural gas at sea is owned and operated by BG and other foreign interests. You're pulling a lazy protester here, assuming that conflict in the Middle East is by default about oil.
And assuming Israel is the pawn here is a massive reach. Netanyahu has been wagging the dog from the beginning, as Israeli governments generally do with the U.S. And his agenda is clear: he is and always has been trying to undermine a Two-State Solution deal, which is why he's supported Hamas and helped them stay in power. Only this time, their attack was so brutal and brazen, he needs to eliminate them because of how incompetent they made him look.
