Journal 69 – The cruel twentieth century

The twentieth century was one of cruelest period in the human history. This century experienced two world wars: the First World War and the Second World War. World War I was lasted from 1914 to 1918, and World War II was lasted from 1939-1945.
The Second World War began on September 1, 1939, when Nazi Germany invaded Poland. During World War II, and after it’s, were killed several dozens millions people. It was estimated that the same number of people could have died because of governmental repressions against its own citizens. The Soviet Union is a good example in this cause.
Unfortunately, prognosis for XX century isn’t optimistic. Many present conflicts have a source in the previous century.
