Guderian argued that the tank would be the decisive weapon of the next war. "If the tanks succeed, then victory follows", he wrote. In an article addressed to critics of tank warfare, he wrote "until our critics can produce some new and better method of making a successful land attack other than self-massacre, we shall continue to maintain our beliefs that tanks—properly employed, needless to say—are today the best means available for land attack." Addressing the faster rate at which defenders could reinforce an area than attackers could penetrate it during the First World War, Guderian wrote that "since reserve forces will now be motorized, the building up of new defensive fronts is easier than it used to be; the chances of an offensive based on the timetable of artillery and infantry co-operation are, as a result, even slighter today than they were in the last war." He continued, "We believe that by attacking with tanks we can achieve a higher rate of movement than has been hitherto obtainable, and—what is perhaps even more important—that we can keep moving once a breakthrough has been made."[154][l] Guderian additionally required that tactical radios be widely used to facilitate coordination and command by having one installed in all tanks.
As the war progressed, Allied armies began using combined arms formations and deep penetration strategies that Germany had attempted to use in the opening years of the war. Many Allied operations in the Western Desert and on the Eastern Front relied on massive concentrations of firepower to establish breakthroughs by fast-moving armoured units. These artillery-based tactics were also decisive in Western Front operations after Operation Overlord and both the British Commonwealth and American armies developed flexible and powerful systems for utilizing artillery support. What the Soviets lacked in flexibility, they made up for in number of multiple rocket launchers, cannon and mortar tubes. The Germans never achieved the kind of response times or fire concentrations their enemies were capable of by 1944.

In the 1930s, Hitler had ordered rearmament programs that cannot be considered limited. In November 1937 Hitler had indicated that most of the armament projects would be completed by 1943–45.[129] The rearmament of the Kriegsmarine was to have been completed in 1949 and the Luftwaffe rearmament program was to have matured in 1942, with a force capable of strategic bombing with heavy bombers. The construction and training of motorised forces and a full mobilisation of the rail networks would not begin until 1943 and 1944 respectively.[130] Hitler needed to avoid war until these projects were complete but his misjudgements in 1939 forced Germany into war before rearmament was complete.[131]

What is clear is the practical implementation of this doctrine in a wide and successful range of scenarios by Guderian and other Germans during the war. From early combined-arms river crossings and penetration exploitations during the advance in France in 1940 to massive sweeping advances in Russia in 1941, Guderian showed a mastery and innovation that inspired many others. This leadership was supported and fostered by the Reichswehr General Staff system, which worked the Army to greater and greater levels of capability through massive and systematic Movement Warfare war games in the 1930s.

Oscar Schindler was all that stood between them and death at the hands of the Nazis. A man all too human, full of flaws like the rest of us. The unlikeliest of all role models - a Nazi, a womanisor, a war profiteer. An ordinary man who answered the call of conscience. Even in the worst of circumstances Oscar Schindler did extraordinary things, matched by no one. He remained true to his Jews, the workers he referred to as my children. He kept the SS out and everyone alive.
British theorists John Frederick Charles Fuller and Captain Basil Henry Liddell Hart have often been associated with the development of blitzkrieg, though this is a matter of controversy. In recent years historians have uncovered that Liddell Hart distorted and falsified facts to make it appear as if his ideas were adopted. After the war Liddell Hart imposed his own perceptions, after the event, claiming that the mobile tank warfare practised by the Wehrmacht was a result of his influence.[142] By manipulation and contrivance, Liddell Hart distorted the actual circumstances of the blitzkrieg formation, and he obscured its origins. Through his indoctrinated idealisation of an ostentatious concept, he reinforced the myth of blitzkrieg. By imposing, retrospectively, his own perceptions of mobile warfare upon the shallow concept of blitzkrieg, he "created a theoretical imbroglio that has taken 40 years to unravel."[143] Blitzkrieg was not an official doctrine and historians in recent times have come to the conclusion that it did not exist as such.[a]
In July 1938, representatives of 32 countries met in the French town of Evian to discuss the refugee and immigration problems created by the Nazis in Germany. Nothing substantial was done or decided at the Evian Conference, and it became apparent to Hitler that no one wanted the Jews and that he would not meet resistance in instituting his Jewish policies. By the autumn of 1941, Europe was in effect sealed to most legal emigration. The Jews were trapped.
Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]

According to Dr. Mordecai Paldiel, the head of the Righteous Among the Nations Department at Yad Vashem: “There was no person more deserving of Righteous Gentile status than Oskar Schindler, including Raoul Wallenberg.” Crowe agrees. “I think that Oskar Schindler’s heroism is unique because of the fact that what he did, both in Krakow and Brunnlitz, took place in the midst of the most horrible killing center in modern history. Moreover, while his most dramatic efforts took place during the last year of the war, Oskar Schindler’s efforts to help and later save Jews was a stance that evolved over three or four years.”
At Auschwitz alone, more than 2 million people were murdered in a process resembling a large-scale industrial operation. A large population of Jewish and non-Jewish inmates worked in the labor camp there; though only Jews were gassed, thousands of others died of starvation or disease. During the summer of 1944, even as the events of D-Day (June 6, 1944) and a Soviet offensive the same month spelled the beginning of the end for Germany in the war, a large proportion of Hungary’s Jewish population was deported to Auschwitz, and as many as 12,000 Jews were killed every day.

The property is of adequate size to ensure the complete representation of the features and processes that convey its significance. Potential threats to the integrity of the property include the difficulty in preserving the memory of the events and their significance to humanity. In the physical sphere, significant potential threats include natural decay of the former camps’ fabric; environmental factors, including the risk of flooding and rising groundwater level; changes in the surroundings of the former camps; and intensive visitor traffic.
Although many people responded with obstructionism and doubt,  several rescue operations were run throughout Axis-controlled Europe. Some were the work of prominent individuals like Raoul Wallenberg and Carl Lutz who worked largely alone while other operations were far more complex. A network of Catholic bishops and clergymen organized local protests and shelter campaigns throughout much of Europe that are today estimated to have saved 860,000 lives. Danish fishermen clandestinely ferried more than 7,000 Jews into neutral Sweden while the French town of Chambon-sur-Lignon sheltered between 3,000 and 5,000 refugees.
After its defeat in World War I, Germany was humiliated by the Versailles Treaty, which reduced its prewar territory, drastically reduced its armed forces, demanded the recognition of its guilt for the war, and stipulated it pay reparations to the allied powers. With the German Empire destroyed, a new parliamentary government called the Weimar Republic was formed. The republic suffered from economic instability, which grew worse during the worldwide depression after the New York stock market crash in 1929. Massive inflation followed by very high unemployment heightened existing class and political differences and began to undermine the government.
On January 20, 1942, Reinhard Heydrich convened the Wannsee Conference at a lakeside villa in Berlin to organize the “final solution to the Jewish question.” Around the table were 15 men representing government agencies necessary to implement so bold and sweeping a policy. The language of the meeting was clear, but the meeting notes were circumspect:
Schindler joined the separatist Sudeten German Party in 1935.[6] Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau.[7] He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.[8]
