Seibersdorf near Vienna, Kneissl also worked as a freelance journalist for German and English-language print media and as a political analyst for the
Austrian Broadcasting Corporation. She authored several specialized and non-fiction books. A quote from her book "My Middle East" also caused controversy. She criticized
Zionism, founded by Austro-Hungarian publicist
Theodor Herzl, as a "blood and soil ideology" based on
German nationalism in the 19th century. as "nonsense". Such remarks led to criticism and caused doubts concerning her self-definition as a "conservative free-thinker", but also gained praise and sympathy from populist anti-migration party
FPÖ, to whose events she was increasingly invited. In 2016, FPÖ leader
Heinz-Christian Strache considered nominating Kneissl as presidential candidate, but eventually decided in favor of
Norbert Hofer instead. After Hofer was defeated by
Alexander van der Bellen, Kneissl criticised Van der Bellen on the occasion of the discussion about the
headscarf ban, doubting his intelligence, character and format. "Not only
Trump, others also provoke", she said, criticizing Van der Bellen and
Pope Francis, who had compared
refugee camps to
concentration camps. == Minister of Foreign Affairs ==
