In order to see anything scandalous on the part of Democrats, Ukraine, etc. some kind of theory (that makes sense to Americans) of how they caused the invasion seems to me to be necessary.
Right up until Russia invaded, all this stuff was just floating around with no explanation, but then it all fell into place. More than a decade of political nonsense now looks like it had one purpose, especially the whole "Hillary the warmonger" line.
If you are Russian or sympathetic, feel free to elaborate on how everything fits together from your perspective.
Sure, lots of people could be corrupt, but one assumes they were corrupted deliberately in service of a singular goal. There's no time-warping back to undo what has happened.
Propaganda can be really masterful, but eventually one has to perform the action that is the point of the whole operation, and then it all falls apart.
An enormous amount of deceptive groundwork was laid for the invasion of France in D-Day, but eventually it happened and then people reacted no matter how well they were diverted.
