After the war, Constandse was hired as a journalist by "Algemeen Handelsblad" editor D.J. von Balluseck, whom he had met in captivity. He came to lead the newspaper's foreign desk, espousing views that ran counter to the Cold War ideology of the time, criticizing both Soviet and US policies as detrimental to world peace. A 1956 editorial in which Constandse argued against Western intervention in the Hungarian Uprising, for fear that it would lead to nuclear war, even caused a scuffle at the paper's news desk.
