The article is silly, claiming that Ukraine has some kind of ‘strategic depth’ when virtually all of their best troops, the ones trained by NATO over the past 8 years, have been or soon will be neutralized by Russia. Ukraine still has a lot of people, since they started with a Ukrainian-speaking population of 30 million or so, but most of them hadn’t picked up a gun until a month or two ago.
Continuing the war only leads to the same result, but with more unnecessary deaths.
