If you live in one of the countries at war, you will inevitably be exposed to “your” side’s propaganda. If you also look at the propaganda produced by the other side, you may well gain valuable information. For instance, if both sides acknowledge the truth of some fact, you can be reasonably sure that that it is the truth (whereas otherwise you might doubt whether your side is telling the truth about that). And if the other side’s propaganda talks about some issue that you’ve never even heard about, it may be useful to research whether something is being concealed by your side.
Even when those writing the propaganda have zero concern with telling the truth, they often will tell the truth, simply because it tends to be more believable. So looking at propaganda may expose you to true statements (which you hadn’t previously considered), which you may be able to confirm are true by independent means.
