The problem with ethics is that if you take almost any two different moral rules, there are always moral dilemmas where it is, for a large minority, unacceptable that we apply one rule over the other. So the moral rules of society as a whole form a logically inconsistent system, which appears to be only consistent within certain boundaries. Since it is inconsistent system, every moral position can be logically invalidated. Therefore, the sensible positions, compromises, are also the least rationally defensible. Now, Chomsky has a humanitarian angle, according to which no harm to other people is justifiable to make the world better. This means he rejects notion of justified war (which is anonymous killing of humans). And from this comes his position on Ukraine.
