One of the unpleasant surprises from the Texeira Ukraine War leak is that the official briefing documents used internally (USA eyes only) took the Ukraine casualty propaganda numbers for themselves and the Russians as legit.
In addition, it appears that the count of Russian vehicle losses was from Orxy - a private group of Ukraine cheerleaders using open source photos.
The USA has a trillion dollar military and a multi-billion Defence Intelligence Agency which supposedly produces this sort of data.
Instead they base on strategy and operational planning on Ukraine War propaganda, and vehicle estimates from the Ghost of Kiev.
No wonder the Counter-Offensive was such a disaster !
As for the Ukraine War, my surmise is that the highest levels of the Biden NSC team have a clear picture of what is going on, with policy driving the intelligence data that is permitted to be circulated at the lower levels. Key US generals long ago projected that a stalemate was the most likely outcome, not a victorious Ukrainian counter-offensive.
