Another solution

From The Murder of Professor Schlick: The Rise and Fall of the Vienna Circle, by David Edmonds, pp. 191-192:

In July 1938 Franklin D. Roosevelt convened an international conference, in Évian-les-Bains in northern [sic] France, to discuss the Jewish refugee crisis . . . [but] the conference, attended by representatives from more than thirty countries, made no progress; there was no loosening of immigration controls. Politicians feared increasing Jewish immigration would be hugely unpopular; four in five Americans were opposed to allowing in a large number of refugees. A poll shortly before the conference in the United States revealed that a majority of Americans believed that the Jews bore at least some responsibility for their persecution. The Australian delegate at the conference summed up his government’s attitude and probably the attitude of others: “It will no doubt be appreciated that, as we have no racial problem, we are not desirous of importing one.”

An indirect consequence of failure at Évian was that the Nazis came to believe that, if foreign states would not take their Jews, they would have to find another solution to the Jewish problem.
