Those in the Israeli Defence Forces: Disobey orders of your superiors. Refuse to fly aircraft, mutiny on your naval ships off the coast of Lebanon and sabotage and destroy their turrets. If reservists, do not accept a call to active duty. If army, refuse combat and do not engage in offensive operations against Hamas or Hezbollah. Your loyalty is not to a criminal state but to yourself. Yes you should accept orders that are of legitimate self-defence. Yes you should attempt to intercept rockets and identify their source. But you should not allow your training as a soldier or sailor or airperson to impose upon you the obligation to carry out orders that are destructive of infrastructure and massive civilian casualties. Disobey your officers, reclaim your honour and walk away from this war of extermination.
Principle IV of the Nuremberg Tribunal, 1950: This applies to you soldiers of Israel and other nations as well that are committing war crimes.
"The fact that a person pursuant to the order of his Government or a superior does not relieve him (or her) from responsibility under international law, provided a moral choice was in fact possible to him (or her)."
