In an interview in a Viennese newspaper in January 1921 , Wilhelm publicly rebuked Poland , condemning the pogroms in Lwów as something that would never happen in a civilized country , and referring to Poland and Poles as dishonorable . This caused a permanent , public estrangement between Wilhelm and his father Stephan . In 1921 Wilhelm published a book of poetry in Ukrainian , '' Mynayut Dni '' ( Минають дні - The days pass )
