Russians were forced to retreat from Kyiv, Russians were forced to retreat from Kharkiv, and Russians were forced to retreat from Kherson.
That's pretty good for fighting the #2 military on the earth(Russia) with no Ukraine navy and pretty much no air-force.
WITH ridiculous rules imposed by the west- Kyiv's strikes with American weapons on Russian territory are forbidden. Resulting in ALL of Ukraine targeted by Russian drones and missiles while Russian military bases just across the border cannot be attacked.
