Amazingly, both France and Britain did not want to believe another world war could happen. Hadn't the war to end all wars just ended in 1918. The US, Britain, and France had dramatically downsized their military and were not interested in developing tanks or new strategy for future wars that were not going to happen(American Senior Military commanders wanted to believe that the horse cavalry would come back and replace tanks and that Airplanes couldn't possibly sink battleships for instance. Hitler knew the Allies didn't want another war and Russia secretly let the German Army train and equip its AirForce and Army to get around the size and equipment limits set by the Allies at the end of WW-1. With caution Hitler started moving his troops along his borders to staging areas. This was forbidden by the allies but the allies did not have the stomach to push the German Military back with force. Hitler now knew the allies had no intention or desire to enforce the limitations, so he then took the next step. He openly mobilized and built forbidden Offensive Weapons(Aircraft, Tanks, War ships, Large Artillary Guns, etc...) and openly started training and equipping the military for large scale offensive Operations. Interestingly, the Russian Army and German Army had a excellent working relationship during this time. Both Armies had a excellent exchange program setup where Russia supplied the Training Areas and Germany supplied the Officers and technician to help Russia fight a modern war. Stalin obviously shared Hitlers plans for future conquest, as displayed by Russias early aggression in ww2. France knew war was coming but hid behind its Maginot Line. The old French Generals prepared to fight a trench war and did not understand that a blitzkrieg was coming. Interestingly, France had a huge advantage in tanks over the Germans. French tanks had better armour, modern communications equipment, and better main guns. But spread them out over the front to support individual infantry units. Which doomed them with the invention of blitzkrie. Britain knew what was coming but like the French didn't want to believe it and didn't prepare. Besides, it still had the worlds largest and best navy(during this time) and knew Britain was safe from invasion. Germany would have to build a navy and this took quite a while, giving the English more time.
Ever heard of wind talkers? well native Americans were used to send codes and whatnot to other companys, theyd speak their native tongue to another native American in some other company, the enemy soon learned about it and it died out quickly, theyd capture a "wind talker" and make them tell them what the code said.
There was nothing uniform about treatment of Nazis.
The party was outlawed in Germany. Many lower and mid level former Nazis took up government/civil service/teacher positions in West Germany.
Higher ups were in some cases held for trial, as at Nuremberg. Many were then executed or imprisoned. There were also other trials, such as the Bergen-Belsen Trials and trials in Poland.
Some fled the country - many going to South America. Many South American countries were led by hardline right-wing or populist militarists that felt an affinity with the Nazis. These Nazis typically went mainly to Argentina, Paraguay or Brazil. Some were sheltered there and lived comfortably for the rest of their lives. Their fate varied widely. Eichmann, for example, was hunted down in Argentina, abducted to Israel, tried and executed.
In eastern Germany the Soviets took over and many ex-Nazis were interned or sent to Soviet camps in Siberia: many never returned.
A few Nazis were tried for war crimes and crimes against humanity, and some of these were convicted and hanged or jailed.
Most Nazis got themselves officially "denazified" by German denazification tribunals - that is they got a document that said that they were basically o.k. and then they "lived happily ever after". Konrad Adenauer's government in Germany in 1950s released many Nazi war criminals very early: after all, ex- and no-so-ex-Nazis could be relied upon to be anti-Communist.Acutely before the war was over the Nazi's made plans and asked most neutral countries that if the war was lost that some of their high commanders could go their and be protected. Most went to Switzerland others went elsewhere but just not to long ago they found one living in Cleveland Ohio so that shows the extent of the plans others were caught and put to trail at the Nuremburg Trials for Crimes against humanity. 24 were put to trial 19 were found guilty and 12 were sentenced to death. 185 others were found guilty in later trials
- While aboard the USS Bonn Homme Richard ( CVA 31 ) in the late 50's I personally observed this being done, with AD's, at almost every port that we entered, especially in Japan. The AD had a prop arc of 13'6" and was rated at 3,350 hp. The AD pilots really did complain, just as shown in the movie.
From a retired air-traffic controller, who was also good friends with several AD drivers.
- If you watch the movie "The Bridges at Toko-Ri" you can see this being done when a carrier comes into port in Japan, as the previous answer says.
