Very moving. Underscores just what was lost forever between 1914-1945. The world lost the best of its genetic stock. Sorry but it is no a surprise that Western civilization is devolving into hedonistic debauchery and committing cultural suicide. The best never procreated.
Pretty sure the House of Habsburg wasn’t the best of our genetic stock. Nor the other inbred royal houses displaced in the time period you describe. Pretty much the opposite in fact.
