Poland’s Military Information Services (WSI) was an intelligence agency with strong links to Russia’s Main Intelligence Directorate which — by resolution of the Polish Parliament — Minister Macierewicz had the duty of disbanding as chairman of the Verification Commission. One of his highest priorities was the creation of new intelligence agencies immune from foreign influence: Macierewicz served as the first head of the newly formed Military Counterintelligence Service.

Stratfor: “The move both removes Soviet influence and consolidates the twins’ power in the government. The release of the WSI report is one of the largest and most decisive moves along these lines. By naming people in the WSI who are connected to Soviet intelligence, Kaczyński ensures their names will forever be known for — alleged or real — Soviet ties. The move undermines the entire structure of the WSI and all of its former personnel, ensuring that it and those attached to it can never recover.”
