In London, Zink was recruited to make broadcasts to his homeland via the BBC Overseas Service, resulting in his family being detained and placed in a concentration camp.
After the war, Zink returned to Czechoslovakia in 1945 and joined the Czech language service of Radio Prague, the international broadcasting station operated by the Foreign Ministry.
Zink's anti-Communist reports were heard by Czechs living abroad and, after the Communist Party of Czechoslovakia took power in a 1948 coup, his broadcasts became anti-government.
Although he was a member of the Ottawa press gallery and his column was ostensibly on national affairs, it was generally a forum for his ardent anti-Communist views.
Zink also ridiculed social programs being introduced by the federal government in the 1960s and 1970s, writing in 1965, "after medicare, what is next on the womb-to-tomb welfare list?
"[2] Zink's columns on federal politics were published in three collections, Trudeaucracy (1972), Viva Chairman Pierre (1977) and What Price Freedom?
