Not a horrible idea, however;
Historically speaking, the Russian war with Finland began with a Soviet offensive on 30 November 1939 — three months after the start of World War II and the Soviet invasion of Poland — and ended on 13 March 1940 with the Moscow Peace Treaty. This was called “The Winter War”.
Prior to that, the only reference I can find to Russia being at war with Finland is The Finnish War was fought between Sweden and Russia from February 1808 to September 1809.
The Spanish Civil War (1936–1939) broke out with a military uprising in Morocco on July 17, 1936 and ended 1 April 1939
