From a similar WSJ article:
“We now estimate 97% of the whole Russian army is in Ukraine,” U.K. Defense Secretary Ben Wallace told the British Broadcasting Corp.’s “Today” show on Wednesday.
Russian forces were trying to advance on all fronts, he said, adding: “We haven’t actually seen this massing of a single force to punch through in a big offensive. We’ve just seen an effort to advance, and that has come at a huge cost to the Russian army.”
Even if they are off, by a LOT, not looking great for the invaders.
