It is helpful to discover that the child who seems irrationally scared of dogs was once bitten by a snarling mongrel. Knowing that Moslem forces were defeated when their siege of Vienna was repulsed on September 11th, 1683, helps make sense of their September 11, 2001 attack on the United States.

After inconceivably vast numbers of casualties, Europe’s first Thirty Years War (1618—1648) ended with the Peace of Westphalia, the foundation of a fierce and formidable nation, Germany.

World War Two broke out twenty years and two months later.
