The thing about Hemingway that people forget is that all the stuff he did was at a time where people weren't traveling that much. At 19 he travels to Italy. He goes to the Spanish Civil War. He goes to China he goes to Africa so at that time to travel that much is really incredible.
Armageddon is not around the corner. This is only what the people of violence want us to believe. The complexity and diversity of the world is the hope for the future.
