Because war is a psyop conducted by the oligarchy against everyone else.
What was the point of the Battle of Britain? Germany had no navy to speak of so was never going to invade England, and England was being supplied by America, so could hold out forever. Yet Germany threw its entire Air Force against Britain until…it was exhausted. Why? What strategic goal could this accomplish? What did it accomplish? It gave The Allies air superiority to enable fire bombing cites and murdering hundreds of thousands of civilians.
Or look at the Normandy invasion, why send wave after wave of infantry against fortified machine gun nests? Unless the goal was to murder wave after wave of infantry…
The purpose of the Ukraine war is murdering young men, the same goal as all wars.
