Circumstances in Europe before the WW2 were totally different from what we experience today. I said in my previous comment. The collapse of the Weimar Republic due in part to the harsh conditions of the Treaty of Versailles left the Germans in dire economic straits. Economic condditions and disillusionment at Italy's treatment by its allies after WW1 helped the rise of nationalism there. Fear of Bolshevism was also a factor in both countries as was the ruthless anti-Catholicism of the Republicans in Spain. I would not judge the people of those days who voted for parties which promised them relief from their miseries and 2nd class status among the nations of Europe. They never foresaw what would come about.
I don't see how reform will bring the millions who have abandoned the Church and its teaching back into it when the 'reform' of 50 odd years ago was what drove them out.  Only a return to the discipline, teaching and liturgy of the pre-Conciliar days can do that in my opinion.
