Are you sure you want to say it's armed conflict? That makes it legitimate to kill members of Palestine Action.
Do you think that's a different understanding of the situation than the one that the state currently has?
Is it not "legitimate" in the same way to kill terrorists?
The labeling of groups as "terrorist" is intended to justify authorization for military action against those groups, where, prior to the Global War on Terror, state affiliation or outright sponsorship was typically needed for a military response.
