I don't think National Socialism was ever condemned by the Church.
I suggest you read Mit brennender Sorge, the Encyclical of Pope Pius XI, which goes so far as to describe Hitler as a 'mad prophet possessed of repulsive arrogance.'

I was hoping you would reply, Jovan. And I was hoping you would mention
MBS. Just becasue the pope had an opinion of a head of a political state does not mean that in and of itself the government of Germany was condemned by the Vatican or elevated to dogma. Yes, yes, yes there is much to criticize in the creature that is National Socialism, mostly that it did not pursue the social reign of Christ nor grant the Church pre eminent status. However, revisionist(read, non pc) history demonstrates that the German Reich of 1933-45 was not bent on world conquest or the extermination of any one particular religion or race. It's sole aim was to make Germany a materialistic, industrial power; it saw Bolshevism and its willing executioners, the Judaics, as credible threats to this.
The United States had no business whatsoever engaging in wars against Germania. And this whole Holocause thing is a pack of lies.
There's no business lie Shoah business.
Interesting. I've just reread the Encyclical, and you're right, of course that there is no condemnation of plans for world conquest or the extermination of any one particular religion or race. Those were still in the future. What the Encyclical is, is a ringing condemnation of National Socialist ideology. I've included a few pertinent quotes for those unfamiliar with the document:
8. Whoever exalts race, or the people, or the State, or a particular form of State, or the depositories of power, or any other fundamental value of the human community - however necessary and honorable be their function in worldly things - whoever raises these notions above their standard value and divinizes them to an idolatrous level, distorts and perverts an order of the world planned and created by God; he is far from the true faith in God and from the concept of life which that faith upholds.
11. None but superficial minds could stumble into concepts of a national God, of a national religion; or attempt to lock within the frontiers of a single people, within the narrow limits of a single race, God, the Creator of the universe, King and Legislator of all nations before whose immensity they are "as a drop of a bucket" (Isaiah xI, 15).
13. We thank you, Venerable Brethren, your priests and Faithful, who have persisted in their Christian duty and in the defense of God's rights in the teeth of an aggressive paganism. Our gratitude, warmer still and admiring, goes out to those who, in fulfillment of their duty, have been deemed worthy of sacrifice and suffering for the love of God.
39. We address Our special greetings to the Catholic parents. Their rights and duties as educators, conferred on them by God, are at present the stake of a campaign pregnant with consequences. The Church cannot wait to deplore the devastation of its altars, the destruction of its temples, if an education, hostile to Christ, is to profane the temple of the child's soul consecrated by baptism, and extinguish the eternal light of the faith in Christ for the sake of counterfeit light alien to the Cross.
