Dear Editor:See The Irish Nationalist And The Nazi: When Eamon De Valera Paid His Respects To Adolf Hitler, by Palash Ghosh, International Business Times
It appears that the following confidential communication was sent by the Irish head of government, Éamon De Valera, to the heads of government of the major Allied Powers about five weeks prior to the end of hostilities in Europe in 1945. I have no doubt that this document will be of considerable interest to diplomats, historians, and the public.
Several weeks after De Valera sent the letter below, he visited the German ambassador to Ireland, Dr Hempel, to express condolences in the wake of Hitler’s death (by suicide). De Valera was widely excoriated for his conduct. But as the correspondence below shows, it was not so much that De Valera was wrong; rather, he just outpaced later, yet-to-emerge modern developments in public international law.
