When Liberals describe a piece of media dealing with contemporary war or politics as being "Morally Ambiguous" they mean nearly always mean that it questions the specific decisions of those in power, not the basic ideological assumptions that their power rests upon. Like it's always "Was it a good idea to invade this tyrannical terrorist shithole in order to spread freedom and democracy?" or "Is it okay to torture evil terrorists shitheads to save people from their oppression", never questioning whether the US actually are protecting the innocent and spreading prosperity or if their enemies really are straightforwardly sadistic oppressors. It may question whether the US is acting like a good guy, but it always affirms that the US inherently is good or at least has the greatest capacity to be. Even in Liberal media where the doesn't come off looking the best, they still make sure to present their enemies as even worse. Not to mention the way that any atrocities the US does commit are presented as either mistakes, malicious perversions of the system (probably orchestrated by enemy infiltrators anyway) or tragic but necessary evils. Meanwhile the atrocities committed by their foes are the proof of their innate evil and strong necessity of stopping them; this is the basis of that whole discussion around whether terrible means should be adopted to achieve the noble end of defeating these villains.

And like a story apparently "isn't making a political statement" when it doesn't give a clear answer on these terms, but the terms themselves are never up for discussion. Like I heard someone call Call of Duty: Modern Warfare "apolitical" because it neither justifies nor condemns stuff like those SAS soldiers torturing Arabs and killing sleeping or unarmed Russians (leaving it for the player to decide oooooooooh sooooo deep), as though its choice of antagonists and decision to present them as unambiguously evil isn't a statement in of itself. And like its choice to give Soviet imagery to the Russian Ultranationlists is apparently just a silly oversight (like ooooh real Ultranationalists hate those Soviet lefties hahaha) that says nothing at all about the creator's view of international politics and anti-US ideologies.

As far as your average Liberal is concerned, media contains political statements are when a character turns directly to the camera and says "This thing is good/bad". Anything else is deep stuff that makes you think and lets you come to your own conclusions. Just play the game, don't worry about who set the rules
