As far as Russia doing poorly, this comes from US and UK intelligence mostly. And well open your eyes - Kyiv is still under Ukrainian control. Other key points are still under Ukrainian control, while some have fallen (for now). Importantly, air space is still contested. That 40 mile long convoy they're keeping an eye on - has barely moved since it was first spotted. Russians are having serious problems with mobility on the ground, and when they do send tanks in, it's with no troop support. This means they are essentially driving around blindly, and can be captured quite easily.
Ukraine is showing some documents that they say were the original plans for the invasion, and it was to go from Feb 20 to March 6... That's total occupation in 2 weeks. So far it's been 1 week and they have barely made a dent (in terms of strategic capture of key points - they are making a big dent in killing civilians and children), and are now starting to bomb and shell a lot more than you'd expect for a 'special operation' meant to liberate their neighbours from nazis.
Maybe this is fake too, who knows for sure... If it helps, just don't believe anything.. Honestly that is an understandable concept.
