If you want a full, comprehensive, scientific, balanced, reasoned, breakdown of how all of Putin’s objectives in the Ukraine fight have now failed this from a US official this week gives some good insight:
Very strong analysis from a strategic point of view.
Anything they have tried has failed and turned to death.
And will continue to do so.
Morale continues to only grow for Ukraine according to all reports on the ground.
With the opposite being the case for the Russia army.
