The correct answer for: One long-standing element of both international law and just war theory is the inviolability of civilians or noncombatants. Is: True
Explanation:
Yes, it might seem difficult to understand but non-combatants are protected by law in war scenarios. Now, this is why certain war leaders are charged for the breakage of truces, human rights and crimes against humanity. Because they break the rules of war. Also, there are certain armies or forces like the ones provided by countries like Mexico, Brazil, The UN that send medics, builders, rescuers, firemen, etc. To help non-combatants involved in crossfire scenarios. They are not armed and wear distinctive of that status and if they are attacked it is a breakage of international war justice. One example of this was in the second world war when the Nazis attacked civilians and forces sent to help them.
The just war theory had existed long before it was put into law. When it was put into law, it was done so with the Geneva conventions which had to be signed by countries and if countries did something against it, like kill civilians, they would get punished severely for war crimes and crimes against humanity. This is a key component of both practices.
