@MisschiefMaker We weren't told the same thing when Russia annexed Crimea in 2014 - no-one I'm aware of said anything remotely comparable. There wasn't a war then, so would have very been hard to claim Russia was losing one - the Russian armed forces may be poorly trained, corrupt and incompetent, but even they would struggle to lose a war against no opponent.
Russia's hold on Crimea is more tenuous now than it has been at any point since annexation. They've had to relocate the bulk of the Black Sea Fleet (the basing for which was a key reason for annexing Crimea) because of the damage the Ukrainians have done to it. They have only been able to hang on to it because of Western anxiety about Russian nuclear threats. Whether that anxiety continues to help Russia will be an interesting question for the next year.
The war as a whole has been an epic disaster for Russia in every conceivable way. They haven't been this diplomatically and militarily weak since the 1990s. Aside from the human cost (which the Russian govt doesn't care about), they spent billions and billions of dollars on a completely unnecessary war that has done it nothing but damage and left it dependent on China - ethics aside, it's the dumbest thing a major country has done in my lifetime.
On who to trust: all media and analysis out of Russia is pure propaganda. Sadly, that even includes academics now - people I used to respect have just turned into mouthpieces for the government. Not surprising though, given the punishments for stepping out of line. There's propaganda by Ukraine too, inevitably, but the reporting from some Ukrainian journalists is good - Illia Ponomarenko of the Kyiv Independent is a good source in my experience. UK newspaper and TV war reporters (the people actually on the ground in Ukraine) are good. If you want detailed analysis of the current status of the war and where it's going, probably the best English language analyst is Michael Kofman (he's on twitter) - he really knows what he's talking about, and his cautious take on things has been annoying less careful people on every side since the start of the war in Feb 2022. But you may not want that level of detail.
