Did you see what happened to the Israeli guy who exposed Israel's nuclear warheads?
Spoiler: the Israelis hunted him down and murdered him in Europe. You don't say shit like this while you work for the IOF terrorists, or they'll fucking murder you
Israelis concerned about morality should refuse to serve in the IDF at all and take the jail time instead.
For those who didn't, they obviously believe in what they're doing to some extent and I'm not convinced that the incentives are really there to do the right thing. What is the consequence for committing the war crime? It is non existent. Straight up. So if you risk punishment by refusing, why would you?
Again, if you have morals you should lay down your arms and fucking leave Gaza immediately. Refusing one order is pointless when there are war crimes committed every day.
Yes, it's a very sticky wicket. In Israel's case you can just be a conscientious objector and either make up an excuse for non-service, or take the jail time. In places that don't even pose as Liberal democracies that's not an option, and you're best off trying to defect to someone else. If you can't manage that either, it's basically just time to survive while choosing kindness wherever you can, even if it means some loss and some risk. The soldier in The Pianist giving the guy cake comes to mind.
Not in the US military, and I'm sure others as well. What civilized nations are you referring to? I can only speak to the US, but enlisted soldiers here take a pledge to follow orders, while the officers are actually the ones to take a pledge to uphold the US constitution.
You are not required to obey an unlawful order and in most militaries you are required not to. If you get court martialed it shouldn't be a problem since you were in the right and not the officer issuing the unlawful order.
