This time lapse video 'World Battleground: 1000 years of war in 5 minutes' by Kolomaire via YouTube is an animation showing important battles. The sizes of the explosions and labels are proportional to the number of casualties.
Tip: If you can’t last the full 5 minutes, fast forward to the 4 minute mark to see the more recent battles and their size and scale relative to conflicts in history.
I don't like reading "To be continued" but ACK the realistic reality,
