Why the power struggle between Ukraine’s two top military geniuses reflects a truth about modern warfare every nation must confront

The article text supplied for this piece could not be retrieved — the content returned consists only of Daily Mail navigation elements and unrelated headline teasers, with none of the actual op-ed by David Patrikarakos on the reported rivalry between two senior Ukrainian military figures. As a result, no factual details about the power struggle, the individuals involved, or its implications for modern warfare can be accurately summarised.

Based on the headline alone, the piece appears to be a comment article examining tensions between two of Ukraine's leading military commanders and drawing broader lessons about command structures in contemporary conflict. However, without the full article text, specific names, events, dates or quotes cannot be confirmed, and a reliable summary of its arguments cannot be produced.
