And church loved that. Pius XII was very chummy with Ustase and after war helped a lot of them avoid justice, and that include Alojzije Stepinac, head of croatian church who was very close with ustase and organized church to support them. He even make Stepinac cardinal after war. Pope John Paul II even beatified Stepinac as a martyr (his "martyrdom" was 5 years in prison and then being confined to one town) and wanted to make him full saint, the process was stopped only by Francis.
