These incidents constitute cold-blooded murder. US drone killings and rampaging death squads, as well as Israel's deplorable history and latest ritual slaughter highlight the issue. International law prohibits anticipatory self-defense. It amounts to using force to deter it.
Under the UN Charter's Article 2(4):
"All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations."Only two exceptions apply. Article 51 permits "individual or collective self-defence if an armed attack occurs against a Member of the United Nations, until the Security Council has taken measures necessary to maintain international peace and security."
In addition, a nation may anticipate self-defense in situations where verifiable, compelling evidence shows imminent or already initiated armed attacks.
Comment: As it has been for a number of years now, a war with Iran has been given the green light. Israel is, once again, creating a "right to defend itself" when in fact Israel has always been a main source of aggression, oppression and brutality throughout the Middle East.
In terms of a 'host' ("I presented the example I just gave you to my hosts in Washington): Germs are not aware that they will be burned alive or buried deep in the ground along with the human body whose death they are causing. -Andrew Lobaczewski's Political Ponerology
