Ukraine used up a massive amount of resources on this. And they've got little left.
However, it's embarassing for Russia as they did get "caught flatfooted" mainly due to "complacency" from so many victories. They fell for a Ukrainian feint. A bit like when the Russians tricked the Ukrainians to put a load of troops into defending Kiev earlier.
But Ukraine are today little better off in the grand scheme of things. As in "where do they go from here?". They've shot their bolt, pretty much, according to Ritter.
There's a lot more there but that's enough to be going on with.
Regarding this being "one of the greatest intelligence failures" by Russia which he describes as "being up there with the failure by the Israelis to predict the Egyptian crossing of the Suez canal during the Yom Kippur war of 1972" is around the 18.50 mark.
Regarding your post "He's got the title wrong then": it's not Ritter's title. He's a guest on the show. It's certainly a crap title. Ignore titles I keep an eye on Ritter.
