Multinationals operate in many different countries, so they have interest in the operation, production and consumption, which includes dealing with labor laws, environmental impact, taxes, etc. Every country is different, but the interest of the corporation is usually the same...profit.

World War 2 which has started in 1939 was the most devastating war the world has ever fought. One of the reasons for that devastation was because the Third Reich forces used a tactic called Blitzkrieg which was designed the following way: At first Dive Bombers went in to strike enemy points (JU-87 Stukas) were the most popular for those missions. After the bombardment went the Wehrmacht (tank) forces and the Infantry. The other devastating problem for the Allies was the new Submarine tactics. Hitlers engineers have developed a submarine known as a U-Boat. Those were mostly used for the blockade of Great Britain to sink allied shipping. The most devastating moment of the war was in 1945 when the United States launched a successful Atomic strike in Hiroshima and Nagasaki causing more then 200,000 casualties from each atomic bomb. In total 75,000,000 people died as the result of battles.
