Hate benefits both sides in thid conflict. In palestine you have a literal terror group running a country, building on hatred on Israel and its treatment of their people.

Any diplomatic effort by Israel (opposition, for example) makes Hamas look bad internationally and possibly to their own people. So you fire a round of missiles into the country and the voices of solving the conflict in Israel die down in the public debate. "Do you want to negotiate with THESE people?"

Vice versa, Israel has a conservative government building on fear of Muslim terrorism and being overrun by their Arabic neighbours. When moderate Fatah tried to extend an oil branch, even just to look better to everyone else, you have some "anti-terror" operation where you level some building in the Gaza strip.

So funny enough, the two arch-enemies Netanjahu and Hamas benefit from each other. They build on hatred and fear and hatred and fear is what they like to spread.

You can decide to put the tinfoil hat on for a moment. These truck attacks are used because they're hard to prevent, obviously. But this attack surely makes everyone in the UN supporting recognition of Palestine look bad.
