WW1 was the greatest crime ever committed in the history of the human race. The wholesale slaughter of an entire generation of men, the punitive Treaty of Versailles, the disastrous Sykes-Picot agreement between France and Great Britain that redrew the map of the Middle East and the rise of the House of Saud gave us Hitler and Islamic Terrorism. I have no sympathy for Europe.
You are correct. The flower of Europe died in WWI. The arbitrary Sykes-Picot treaty which ignored tribal,religious and political differences is unraveling and is the source of most of the strife in the Middle East today.
