the full quote, which is actually quite accurate and succinct:
“Because of racism, that’s the simple answer I would say. Racism, and uh, basically, desperately trying to defend a destructive deadly system, that systematically puts short term economic profit, and to maximize geopolitical power, over the well being of humans and the planet. And right now it’s very very difficult to morally defend that, it is impossible, but still, they are desperately trying which is… absurd is not the word, but there are no words to describe it.”
The choice is between imprisonment/discharge and participating in the actions of the fascist war machine. Is obeying orders worth ruining the rest of your life with the knowledge and scars (physical + mental) that stem from them?
You do still have agency, the choice is just between being punished for doing the right thing, or participating in something illegal and monstrous with the slim chance of never being punished for it. Even if that punishment never comes, the internal torment and external judgement will be unavoidable.
Seriously, there is absolutely no disguising what is being defended here, the israelis have been starving, torturing, and murdering Palestinian children for over 600 days. There is no shortage of evidence of their heinous conduct. If someone is ordered to participate in an illegal war of aggression on their behalf, it is their moral and ethical duty to disobey those orders.
