Winter War
The official figure was 611 tank casualties, but Yuri Kilin found a note received by the head of the Soviet General Staff, Boris Shaposhnikov, reporting 3,543 tank casualties and 316 tanks destroyed. According to Finnish historian Ohto Manninen, the 7th Soviet Army lost 1,244 tanks during the breakthrough battles of the Mannerheim Line in mid-winter. In the immediate aftermath of the war, the Finnish estimate of the number of lost Soviet tanks was 1,000 to 1,200. The Soviet Air Forces lost around 1,000 aircraft, but fewer than half of them were combat casualties. According to Carl Fredrik Geust, based on the studies of Soviet air force units, Finnish anti-aircraft units shot down 119 and Finnish fighter pilots 131 Soviet aircraft, though all Soviet aircraft losses had been more than 900.

Germany: The Winter War was a political success for the Germans. Both the Red Army and the League of Nations were humiliated, and the Anglo-French Supreme War Council had been revealed to be chaotic and powerless. The German policy of neutrality was unpopular in the homeland, and relations with Italy had suffered. After the Moscow Peace Treaty, Germany improved its ties with Finland, and within two weeks, Finnish-German relations were at the top of the agenda. More importantly, the very poor performance of the Red Army convinced Hitler that an invasion of the Soviet Union would be successful. In June 1941, Hitler declared, "we have only to kick in the door and the whole rotten structure will come crashing down".

Allies: The Winter War laid bare the disorganisation and ineffectiveness of the Red Army and that of the Allies. The Anglo-French Supreme War Council was unable to formulate a workable plan, revealing its unsuitability to make effective war in either Britain or France. This failure led to the collapse of the Third Daladier Government in France and the nomination of Paul Reynaud as the new Prime Minister of France.
