There are a few more points to add to what has been said above:

After the end of World War II, in accordance with the agreements signed at the 1947 Paris Peace Conference, Bulgaria - as an ally of Nazi Germany - was required to pay reparations totaling $70 million over an eight-year period. However, this is mere pocket change compared to the billion dollars that Greece, actively egged on by the British, wanted to squeeze out of Sofia! And it would have succeeded - had the USSR not intervened to stand up for its “brothers.”
