Why Die for Danzig?

Why Die for Danzig? (Pourquoi mourir pour Dan(t)zig?, Dlaczego musimy umierać za Gdańsk?) is an anti-war French political slogan created on the eve of World War II.

Article
The phrase originated in the title of an article (Mourir pour Dantzig?) by French socialist writer Marcel Déat, published on May 4, 1939 in the Parisian newspaper L'Œuvre. The article concerned one of the Nazi Germany ultimatums for the Second Polish Republic, regarding the demand to transfer control of the Free City of Danzig (Gdańsk) to Germany. In the article, Déat's argued in favor of the appeasement policy. He asserted that France had no interest in defending Poland, and that Hitler would be satisfied after receiving the territory he (rightfully, according to Déat ) demanded. He accused the Poles of warmongering and dragging Europe into a war. Déat argued that Frenchmen should not be called to die paying for irresponsible Polish politicking, and expressed doubts about whether Poland would be able to fight for any significant amount of time.

Impact
Opinions on the significance and the impact of the slogan differ. The article and several similar pieces were noticed by diplomats and government officials, French and foreign, and elicited press releases from Prime Minister Édouard Daladier and Foreign Minister Georges Bonnet, who noted that this sentiment did not represent the majority views of either the French public and the French government, and reaffirmed their support for the Polish-French alliance.

The slogan has been credited by Henry Kissinger with demoralizing the French in 1940, but historian David Gordon argues that it was mostly marginalized by that time. Historian Julian T. Jackson agrees, noting that while the slogan was taken up by some extremist groups, such as the British People's Party, for the most part at the time of being written it "fell largely on deaf ears". According to historian Karol Górski, Déat's article, and the resulting slogan, gained some popularity in France and abroad, and others list the groups among it resonated, such as the French intelligentsia, far right and isolationists. It was however less popular among the general public; Thomas Sowell cites a French poll around that time showed that 76 per cent of the public was supportive of going to war over Danzig.

This slogan was particularly negatively received in Poland, and entered the Polish language as the phrase "umierać za Gdańsk", used as a type of an informal fallacy, describing an argument nobody should agree with. It still appears in Polish political discourse and appears as a reference recognized by general public as of 2012. A number of modern Polish sources cite this slogan arguing it was the dominant view shared by majority of Frenchmen and even the British, claiming that the general mood of those countries was such that their citizens did not want to fight for their Polish ally. However other modern Polish sources debunk this. The phrase has also been occasionally used in modern French and English language political discourse. Back in 1939, the phrase was readily adopted by Nazi German propaganda, and used in French language broadcasts around the time of the Phoney War.

Following French defeat by Germany and the creation of the Vichy regime, Déat became an advocate of fascism and a Nazi collaborator, going so far as to look for support in Nazi Germany for his fascist party, which was more radical than the Vichy regime.
