Frankfzurte rRundschau published this image to illustrate the advance of Ukraine June 7th to today.
A "breakthrough looks different.
I think Kyiv exaggerated their successes a bit...

And wasnt it said they "breached the third defenc eline of the Russians? All I see on that illustration is they merely broke through the second, and are a good way away from the third.
They overwhelmed some serious defences -
at unknown costs for themselves. A breakthrough this is not.
