Quotewhat you're saying is if you're weak and succumb to the propaganda (i'm sorry but it is), then yes, you will be able to shoot people without any moral obligations.
I wouldn't really characterise it as 'propaganda'. It's not really an ideological thing -- it's simply teaching someone to be better at their job via responding to an input with an targeted response.
Quoteif you have absolutely no inclination whatsoever, you will be smart enough not to be put into battle in the first place.
If you're a soldier who is conscripted / drafted and you want to survive, it is in your best interests to soak up the training and give yourself the best chance of surviving. I agree that this sort of conditioning is quite scary, but war is fucked up in general. Even famous people and established sportsmen often have to do their service in countries that have mandatory service; it's not like everyone who doesn't want to fight can just duck out of it and they'll be excused. I would never want to join the army and potentially have to hurt or kill others, but if I was drafted and there was the possibility that I would be placed in situations where my life and the lives of my friends would be at risk, I would want to come out alive, even if it meant the enemy (faceless or otherwise) would not.
You are definitely correct regarding the potential for post-traumatic stress, guilt and various other mental issues that come after a tour of duty, but you have to survive the battlefield first and worry about that later. There's various things that can be done to manage it, but it's still an ongoing area of research. In typical human fashion, we are pretty damn good at conditioning to kill & destroy, but repairing the damage is almost like an afterthought.
I'm not trying to say that this sort of training is moral or immoral, just that is necessary if you want to be a 'good' soldier.
