Her autobiography does not mention her husband, Robert Tabouis [fr], and refers only in passing to her son, who was called up into the French army in 1938, and to her daughter.
In 1933, she accompanied French Prime Minister Édouard Herriot who travelled to Moscow in an effort to forge a Soviet-French alliance against Germany.
After Germany announced that it was re-introducing compulsory military conscription and rebuilding its armed forces in March 1935, the Greek diplomat Nikolaos Politis warned her "You better watch out, Madame Tabouis, or they'll begin to call you Cassandra.
Le Petit Marseillais (whose director was married to a Spanish Fascist) asked her to "modify" her tone—she left that paper as well.
Tabouis became the foreign editor of L'œuvre in 1936, where her pro-Republican stance lead to attacks by the Parisian weeklies Candide and Gringoire as well as Action Française.
She strongly supported intervention to prevent the German occupation of Czechoslovakia, but the French chose not to intervene.
On the eve of World War II, she was a regular correspondent for London's Sunday Referee in addition to her role at L'œuvre.
In 1938, Life magazine reported that Tabouis was a non-smoker, teetotaller and vegetarian, and in a surgical operation had to have a kidney removed.
