[5] Schmidt's scholarship and relationship to successive governments of Hungary has come under intense criticism in the English and Hungarian public press and among scholars.

[7][8] Andras Heisler, president of the Federation of Hungarian Jewish Communities, criticised Schmidt's "untrustworthy account of Holocaust history", resigning from the project.

[9] Randolph L. Braham, leading scholar of the Holocaust in Hungary, returned his honors from the Hungarian government and also criticized her for the "wave of historical revisionism bolstered by Schmidt's work".
