You won't prove it to those who don't want the proof. Just clean up the place and build what's needed, let those who "know better" to keep claiming they're the masters of the universe.
The war's been at a stalemate for over a year with Ukraine having lost control of its eastern provinces in spite of receiving hundreds of billions of dollars in aid from "the West". Sounds like a loss to me, regardless of one's personal feelings.
Stalemate is not loss. Kyiv still standing is not loss. The loss could've been way worse months ago. Both sides are still planning action. "Lost" is disrespectful to people on the ground still fighting and risking lives every day.
True, but let's not forget that the US Defence Secretary Lloyd Austin declared the US goal in Ukraine is to 'weaken Russia'.
Puts a different perspective on what winning means.
