Page "World War II" Paragraph 34

Following the invasion of Poland and a German-Soviet treaty governing Lithuania, the Soviet Union forced the Baltic countries to allow it to station Soviet troops in their countries under pacts of " mutual assistance.

" Finland rejected territorial demands and was invaded by the Soviet Union in November 1939.

The resulting conflict ended in March 1940 with Finnish concessions.

France and the United Kingdom, treating the Soviet attack on Finland as tantamount to entering the war on the side of the Germans, responded to the Soviet invasion by supporting the USSR's expulsion from the League of Nations.
