The United States and Great Britain during World War 2 (1939-1945) signed the Atlantic Charter that set a vision for the post-war world with support from 26 Allied Nations which became one of the first steps towards the establishment of the United Nations.
On 14th August 1941, The Atlantic Charter was issued by the then U.S president Franklin Roosevelt, and the British Prime minister, Winston Churchhill. It had broad statements of British and U.S war aims and affirmed the solidarity of the two against the Axis aggression and further laid a foundation for president Roosevelt vision for the post-war period; Free exchange of trade, disarmament, collective security, and self-determination.
The charter further served as an inspiration for thirds world countries that fought for independence i.e. Vietnam, Ghana
The Germans thought Calais was the likely landing site for an Allied invasion because the Allies made them think that's what they were planning.
The Allies employed various strategies, code named "Operation Fortitude," which were intended to deceive the Germans in advance of the planned Normandy invasion. They built up phony infrastructure for possible invasions, on at Calais just across the English Channel, another as a northern incursion via Norway. They also leaked phony intelligence reports that would find their way into German hands. So Calais seemed logistically sound not only because it was directly across the Channel from Allied positions in Britain, but because the Allies were wanting the Germans to think that was a possible plan they were making. The deception was meant to give the actual invasion at Normandy a better chance for success.
The 18th Amendment and the Volstead Act were victories for the long enduring cause of Prohibition. Those two pieces of legislation banned the sale and distribution of alcohol within the United States, which inadvertently gave rise to bootleggers and organized crime as people continued to try to get their hands on alcohol during the 1920s and into the 30s before the passage of the 21st Amendment which repealed the 18th.
