Why Russia has not raised the issue of the genocide of the siege of Leningrad?

As I understand it, but nyunbergskom process raised the issue of the siege of Leningrad, but was removed. Someone suggests that a full blockade was not (still over the years the enterprises of the city produced weapons in mass quantities, and this should have been resources that are explicitly supplied in the water). And someone says that a party of the USSR did not recognized the hunger, and therefore could not be considered genocide. And someone said that hunger was not at the time spelled out in the Convention. \r\n\r\n\r\n\r\NIN General, to repeat, the investigation will need to declassify documents to prove that 60 km of coast available for the delivery of goods and people are not free corridor (although fire).
