Well, Israel certainly doesn't intend to destroy Arabs, Muslims, or brown-skinned people more broadly, and you can't honestly claim "Palestine" is a nation:

- no defined territory--and certainly none widely recognized

- no unique language or ethnicity

- a culture only distinguished from Egypt and the Levant by their penchant for terrorism

- a history that only meaningfully diverged from their neighbors within the last half-century, and which divergence springs entirely from their consistent unwillingness to pursue peace with Israel

So even if Israel had the intent to commit genocide--which, unfortunately[1], they don't--the Arabs in Gaza don't qualify as a distinct group that can be subjected to genocide.

If Colombia had decided to annihilate the FARC, just kill them all--would that have qualified as a genocide, too? It seems to me they meet at least as many tests for nationhood.
