Retired Gen. David Petraeus, who commanded US forces in the Iraq and Afghanistan wars, says the Russians are facing a Ukraine military that is exceptionally determined, surprisingly capable and innovative, and one that is fighting on its home territory for its very survival.

In contrast, the Russian invaders have displayed a host of weaknesses: flawed planning; overly optimistic intelligence projections about how the conflict would play out; underestimation of the Ukrainian forces and people; inadequate maintenance and logistics; unimpressive equipment; a reliance on conscripts and an inability to mount effective cyberwarfare.

He predicts the most likely near-term outcome of the war in Ukraine will be the continuation of a bloody quagmire for Russia that is largely indecisive, even as it inflicts greater and greater loss of life, infrastructure and basic services on the Ukrainian people. There is, however, also the possibility of a negotiated resolution, as both Moscow and Kyiv recognize the damage and destruction being done to their countries.
