I took this from the internet:
Even the hallowed D-Day invasion is not untainted. About 3,000 French civilians died on D-Day – about the same number as American soldiers killed in the invasion. All told, hundreds of tons of Allied bombs were dropped during the “liberation” of Normandy, destroying fields and livestock, obliterating towns and villages, and killing 20,000 civilians.
The conduct of American forces during the war, and in some cases after the war, was sometimes shameful. After the D-Day invasion, some members of the “greatest generation” engaged in drunkenness, carousing, vandalism, petty thefts, looting, seizing property as trophies, robbery, trafficking in stolen military goods, wasting scarce food and drink, billeting themselves in private homes, sexual assault, rape, and gang rape of women of all ages, and mistreating, assaulting, and otherwise abusing their power over those they liberated in France, Belgium, and Germany. Venereal disease and prostitution were rampant, as you can imagine. None of this matters, of course, because we were fighting Hitler.
But after we were done fighting Hitler, American soldiers participated in the forced repatriation of hundreds of thousands of Russian POWs to the Soviet Union, where many were killed or sent to the gulag, and the mistreatment and neglect of German POWs.

Churchill the smoking drunkard.
I got the following from: http://www.welcomearmenia.com/main.php?lang=eng&page=armeniainformation&sid=19
it was in 1945 when a special 50 degree cognac “Dvin” was produced in Armenia for the Yalta Conference. Sir Winston Churchill asked J. Stalin for a batch of cognac. With a thoughtful look, Stalin answered: “The Soviet Union has full supply of Armenian cognac, so it may as well be sold”. Since then the periodic delivery of “Dvin” to the British Prime Minister had been controlled by the “Father of Nations” personally. In his written requests for subsequent batches Churchill persistently called the cognac by Shustov’s name, while the Russian side patiently corrected: “former Shustov’s cognac”. The legal delivery to England continued until the beginning of the cold war. Afterwards, the Russians refused to supply Churchill with that dainty. However, Churchill’s passion for cognac turned out to be stronger than his political ambitions. Only God knows how he continued receiving his favorite drink. And when aged Churchill was asked about the secret of his longevity, he answered without hesitation: “Never be late for dinner, smoke Hawaiian cigars and drink Armenian cognac!”
