As World War II progressed, some of the brutal designs and tactics that were planned at the beginning of the war, progressed and became even more brutal. The final solution plan begun by Germany had originally been comprised of Germans shooting large amounts of Jewish people. When this took too much work and took too much of a toll on the soldiers, Nazi leaders decided to go with a work camp plan. Gas chambers would be set up in order to be able to kill more people who could not work, and those who could work would be sent on to the concentration camps, the center of the camps being Auschwitz. Other than Jewish people, the Nazis went after other people they considered lesser humans. Many Slavic people and Polish civilians were killed, as well as Soviet POWs. Thousands of Yugoslavians were killed in reprisal shootings, and a large percentage of Jehovah’s Witnesses were killed.
Something that many military leaders thought was that the airforce would be the end all be all of warfare. Indeed many new tactics were employed in the airforce in World War II. One of the main tactics of both the Allied and Axis powers was bombing civilians and factories. Especially the Allies thought that if you bombed enough civilians, they would get tired of being bombed all the time and urge the government to surrender. When the Allies after the war took surveys of places that had been continually bombed, however, they found that the effect was to make the people angry and strengthened their resolve not to surrender. When factories were bombed they could usually be rebuilt quickly. One of the more effective strategies was to bomb railroads, so that even if the supplies were made the military could not get them. As the war progressed brutal tactics were employed on both sides to result in general mass destruction.
