Lots of genocides have been carried out with primitive weapons, even recently. Remember, the protesters in Iran were mostly unarmed...
All this is just a excuse, when this whole war is about Israel's national security interest and hegemonic ambitions. The "negotiations" were entirely over the Nuclear program, ballistic program and proxy forces - The protestors, human rights, democracy none of it were even mentioned. Netanyahu didn't visit the White House 6 times over the last year to advocate for the protestors.
