[4] The manifesto prompted heavy concerns from the still newly emerged Ba'athist regime of Iraq, especially in relation to the party's activities with leaders of the Chaldean Catholic Church.

[citation needed] In 2000, the Ba'athist government arrested Assyrians from Mosul and Baghdad after they were found to have obtained pamphlets from the party.

It also contested the January 2005 Iraqi legislative election as part of the Kurdish alliance, and Goriel Mineso Khamis was allocated one seat in the Council of Representatives of Iraq.

[9] In the Iraqi governorate elections of 2009, the BNDP allied itself with the Chaldean Syriac Assyrian Popular Council in the Ishtar Patriotic List.

[11] Similarly, in the 2013 Kurdistan Region parliamentary election, the party ran as part of a Chaldean Syriac Assyrian United List, which also received no seats or representation.

[12][13] The force had been stationed in the Tal Qasab village north of Mosul, and was intended to liberate Assyrian/Christian areas from ISIS while acting as the basis for security for an Assyrian autonomous region.

Hakkari and the BNDP also took part in signing a collective document of support for the KRG, condemning the federal Iraqi government's military actions in the midst of the 2017 Iraqi–Kurdish conflict.

[21] The party, as well as Romeo Hakkari himself, were also criticized by the Assyrian Democratic Organization for their affiliation with Kurdish groups during Iraqi elections.

Romeo had been chosen as head of the National Union Coalition[23] by the KRG, and in 2020, called on Masrour Barzani to provide proper infrastructure for Assyrian villages in Iraq, particularly in the Nahla valley.
