Intelligence officials have cited multiple instances in which Russian troops received direct orders to kill prisoners of war. According to HUR, these acts are not isolated incidents but part of a deliberate and systematic policy of the Russian leadership.
This pattern of war crimes has also been confirmed by the U.N. Independent International Commission of Inquiry on Ukraine. In a report released on March 19, the commission found a growing number of cases in which Russian forces deliberately killed or maimed Ukrainian soldiers who had surrendered or attempted to surrender.
The issue is that US and EU trickled and support and Ukraine lost initiative. It 3+ years in, the materiel is still being trickled.
Ukraine is unwilling being ground into nothing. It seems like they will keep fighting until proper support comes or they are all dead.
Between blind support for Israeli genocide and link dick support for Ukraine, the rules based international world order is just a clown exercise. Prolly always has been but propaganda can no longer maintain the image of propriety.
