Part of it is consuming extremes from both sides and figuring out the Venn diagram of the truth based on what both parties are acknowledging. You can also look at a variety of commenters who are reasonably middle-ground in their analysis. On YT, for me, I consume Perun (pro-Ukraine but largely factual analysis), WillyOAM, Military History Visualized, and History Legends (comes across kinda pro-Russia). I also like the ( https://old.reddit.com/r/UkraineRussiaReport/ ) subreddit, which has Russian-leaning mods, oddly making it perhaps the least-biased subreddit on the war (everywhere else is a DEEP pro-Ukraine echo chamber, including r/combatfootage). For general reasonably-non-biased news, avoid r/worldnews and visit...... r/anime_titties (note the underscore). Seriously, that's a news aggregator subreddit.
