The War of the World: Twentieth-Century Conflict and the Descent of the West

The title suggests a global struggle, but I wonder how the author balances different regions' perspectives and events across such a vast timeline.

With so much ground covered, I sometimes wished for deeper dives into specific conflicts. Was that a deliberate choice to prioritize overview over detail?

Given the enormous scope of history, I'm curious about the criteria used to select certain events over others and how that shapes the overall narrative.
