Former top U.S. commander says Russia cannot “out-suffer” the Ukrainians
Russia still occupies roughly 18 percent of Ukrainian territory in the southern and eastern corners of the country, and the counteroffensive is aimed at driving those forces out. For his part, Russian President Vladimir Putin has vowed to fight until Russia controls more land - including all four of the Ukrainian regions he annexed last September.
Petraeus sees virtually no chance of that happening.
"I don't think there is a realistic end state that he [Putin] can achieve, that his forces can achieve, that could be presented as victory, unless U.S. and Western support for Ukraine collapses," he said. "As long as that support remains steadfast, I think Russia's in a very difficult position."
"I don't think the manpower advantage is as significant as it sounds – and beyond that, Russia is running out of material to provide to their new conscripts," he said. "They've lost well over half of their original tank fleet – and they're in such a dire situation that they are bringing essentially World War II-vintage tanks out of storage and giving them to the units now to provide replacements for those tanks."
Ultimately, Petraeus said, the Russians cannot "out-suffer" Ukraine - a reference to the ways in which Russian and Soviet soldiers in past conflicts have managed to win long wars of attrition.
