Unfortunately, regardless of any philosophy on morality, it is simply unrealistic to expect the citizens of a nation being invaded - a word applicable here without even the merest qualification - to not call for the violent repulsion of the invader, loudly and in great numbers, regardless of how "good" or "bad" the invader's justification is.

Edit: To reconnect my point to the topic - the weight of millions of simultaneous lamentations under such a real, physical attack is simply heavier than the weight of a content policy of a media designed for people to talk to each other. It would be difficult, both morally and practically, to not make an exception in this case. Content policies can not be immutable, and should not be.
