Why was World War 1 more destructive than earlier wars?
New technology. Weapons which had never been used before were
killing men by the thousands on both sides. Also, the 4 year
stalemate due to trench warfare (neither side could get ahead of
the other). Tactics were also outdated. An example of this was in
the Battle of the Somme, where the generals sent waves and waves of
men at walking speed to their inevitable death.
