You basically have to be a perfect victim when you're living with such an L.I feel you. But the equal population size means nothing when you're so technologically inferior. The fire power and training of one IDF solider is equal to that of potentially 4-5 HAMAS and 10+ Palestine civilians. Numbers are irrelevant here.
I've usually been pro-Palestine, but you CANNOT bomb innocent people in concert halls and festivals and expect the world to be on your side. Flat out. These weren't hardened military or even state targets.
Israel now has a full blown casus belli to wipe Gaza off the map and take it over completely. HAMAS has basically signed the Palestinian state's death warrant.
Gaza just chose the suicide option.
