In 1939 the Soviet Union signed a non-aggression pact with Nazi Germany, making the transport of Jews from Europe to Japan far more difficult. The events of 1940 only solidified the impracticality of executing the Fugu Plan in any official, organized way. The USSR annexed the Baltic states, further cutting off the possibilities for Jews seeking to escape Europe. The Japanese government signed the Tripartite Pact with Germany and Italy, completely eliminating the possibility of any official aid for the plan from Tokyo.
