"President of Palestine, Mahmoud Abbas: "We have the right to defend ourselves against Israel and settler terrorism"

Surely, he is correct in that statement.

Israel is a right-wing expansionist state. They do not deserve our support.
I'm not sure Palestine does either, but they should be allowed to peacefully exist as a normal state.
'Settlers' are also a form of state terrorism without a way for Palestinians to object legally.
Of course they will seek opportunity to strike back by other means.
