were balanced between East and West until the fall of the Soviet Union. Assessment Finland and Nazi Germany During the Continuation War (1941–1944) Finland's wartime government claimed to be a co-belligerent of Nazi Germany against the Soviet Union, and abstained from signing the Tripartite Pact. Finland was dependent on food, fuel, and armament shipments from Germany during this period, and was influenced to sign the Anti-Comintern Pact, a less formal alliance than the Tripartite Pact seen as by the Nazi leadership as a "litmus test of loyalty". The Finnish leadership adhered to many written and oral agreements on practical co-operation with Germany during the conflict. Finland was one of Germany's most important allies in the attack on the Soviet Union, allowing German troops to be based in Finland before the attack and joining in the attack on the USSR almost immediately. The 1947 Paris Peace treaty signed by Finland stated that Finland had been "an ally of Hitlerite Germany" and bore partial responsibility for the conflict. Finland was an anomaly amongst German allies in that it retained an independent democratic government. Moreover, during the war, Finland kept its army outside the German command structure despite numerous attempts by the Germans to tie them more tightly together. Finland managed not to take part in the siege of Leningrad despite Hitler's wishes, and refused to cut the Murmansk railway. Finnish Jews were not persecuted, and even among extremists of the Finnish Right they were highly tolerated, as many leaders of the movement came from the clergy. Of approximately 500 Jewish refugees, eight were handed over to the Germans, a fact for which Finnish prime minister Paavo Lipponen issued an official apology in 2000. The field synagogue operated by the Finnish army was probably a unique phenomenon in the Eastern Front of the war. Finnish Jews fought alongside other Finns. About 2,600–2,800 Soviet prisoners of war were handed over to the Germans in exchange for roughly 2,200 Finnic prisoners of war held by the Germans. In November 2003, the Simon Wiesenthal Center submitted an official request to Finnish President Tarja Halonen for a full-scale investigation by the Finnish authorities of the prisoner exchange. In the subsequent study by Professor Heikki Ylikangas it turned out that about 2,000 of the exchanged prisoners joined the Russian Liberation Army. The rest, mostly army and political officers, (among them a name-based estimate of 74 Jews), most likely
