text_A: Some Western experts believe the evidence released from the Soviet archives is understated, incomplete or unreliable. Conversely, historian Stephen G. Wheatcroft, who spent a good portion of his academic career researching the archives, contends that, prior to the collapse of the Soviet Union and the opening of the archives for historical research, "our understanding of the scale and the nature of Soviet repression has been extremely poor" and that some specialists who wish to maintain earlier high estimates of the Stalinist death toll are "finding it difficult to adapt to the new circumstances when the archives are open and when there are plenty of irrefutable data" and instead "hang on to their old Sovietological methods with round-about calculations based on odd statements from emigres and other informants who are supposed to have superior knowledge."
text_B: If Western experts had first hand access to the Soviet Archives, would they likely find more evidence?
YES.
