Why is "Catholic Church and Nazi Germany during World War II" trending?

Wikipedia Overview

Several Catholic countries and populations fell under Nazi domination during the period of the Second World War (1939–1945), and ordinary Catholics fought on both sides of the conflict. Despite efforts to protect its rights within Germany under a 1933 Reichskonkordat treaty, the Church in Germany had faced persecution in the years since Adolf Hitler had seized power, and Pope Pius XI accused the Nazi government of sowing 'fundamental hostility to Christ and his Church'. The concordat has been described by some as giving moral legitimacy to the Nazi regime soon after Hitler had acquired quasi-dictatorial powers through the Enabling Act of 1933, an Act itself facilitated through the support of the Catholic Centre Party. Pius XII became Pope on the eve of war and lobbied world leaders to prevent the outbreak of conflict. His first encyclical, Summi Pontificatus, called the invasion of Poland an "hour of darkness". He affirmed the policy of Vatican neutrality, but maintained links to the German Resistance. Despite being the only world leader to publicly and specifically denounce Nazi crimes against Jews in his 1942 Christmas Address, controversy surrounding his apparent reluctance to speak frequently and in even more explicit terms about Nazi crimes continues. He used diplomacy to aid war victims, lobbied for peace, shared intelligence with the Allies, and employed Vatican Radio and other media to speak out against atrocities like race murders. In Mystici corporis Christi (1943) he denounced the murder of the handicapped. A denunciation from German bishops of the murder of the "innocent and defenceless", including "people of a foreign race or descent", followed.
