World War I was supposed to the “War to End all Wars“. However many years later World War II followed. The death toll in WW II was enormous with millions of lives lost on the allies side and the enemies side. After WW II new smaller wars led to more deaths.
I came across a fascinating chart today that showed the death toll for each country in WWII. Unlike so many other charts on the web, this chart puts the toll in perspective since it measures the casualties as percentage of each country’s than total population. Based on this logic, the countries with the largest death toll were Poland, Soviet Union and Yugoslavia.

At 0.30%, the U.S. had the lowest death toll percentage as a percentage of total population at that time. This does not mean American sacrifices were small compared to other countries. In fact, 450,000 Americans lost their lives and the US was the main driving force among the western allies. In addition, millions of American soldiers were injured and suffered as well. The sheer US military power and technological superiority helped European countries and the world put an end to the senseless war.

An excerpt from the above article:
The human cost of World War II exceeded by far that of the First World War. Military deaths totaled twenty-two to twenty-five million, including the deaths of five million prisoners of war. Let us examine the death tolls suffered by a number of countries most directly involved in the maelstrom. Poland lost more than 16 percent of its population. The Soviet Union lost approximately 14 percent. Eleven percent of the population of Greece was killed. Other countries that lost at least 10 percent of their populations were Lithuania and Latvia. Other countries that lost at least 3 percent of their people were Estonia, Hungary, the Netherlands, Romania, Singapore and Yugoslavia.
