It astounds me that even in 2026 people are still regurgitating this standard-issue Russian propaganda canard about "Ukraine already lost the war", consciously or subconsciously. While the war is going on, you can make equally vacuous claims that "Russia already lost the war" with about as much cause.
Ukraine is fighting for its survival against a fascist and colonialist invader that aims to end its nationhood. The final outcome is unclear.
It's not a moral statement, Ukraine has fewer bodies and will run out first in a grinding war of attrition.
