@ned Obviously a lot of Israelis did survive the Holocaust to bomb people because it's been happening for various reasons (some justified, some not) since shortly after WWII ended and Israel was created.
It's probably being too charitable toward humans in general to assume that going through something like the Holocaust would automatically make someone a pacifist. I could see quite the opposite happening where many such folk would feel the need to be overzealous in defending themselves to make sure they don't fall victim again.
