At some point, they are going to have to admit that Pius XII put the guys in place to get us to V2 and he's not some glorious pope. History is hard to argue with.
Yes. While Pius XII was certainly a legitimate pope, his was the watershed papacy that led directly to Vatican II.
Pius XII:
1) appointed, during his protracted reign, nearly every bishop who would brings us the glories of V2
2) opened the door the evolution
3) opened the door to NFP as "Catholic Birth Control" (even if one agrees with his position, he didn't clarify it to prevent it form turning into what it has)
4) failed to consecrate Russia to the Immaculate Heart of Mary (which would have prevented Vatican II)
5) rolled out the proto-Modernist Holy Week Rites (rejected as contamined with Modernism by many of the SVs that at the same time promote SH as if it were a solemn dogmatic definition)
6) began allowing various liturgical experimentations (such as the "Mass of the Future")
7) permitted some of the first Ecuмenical meetings
Pius XII enabled and set into motion what happened at Vatican II.
Now, I believe that from about 1955 on, his health collapsed (possibly due to poisoning) to the point that he left the day-to-day administration of the Church to the curia (within which had been entrenched some obvious Modernists, and likely even Masonic / Communist infiltrators).
If a Pope does absolutely nothing else during his entire reign, his #1 job is to appoint good, solid, orthodox bishops. Instead we get the likes of "No salvation outside the Church? Nonsense." Cushing. You're telling me that no orthodox priests could be found to be appointed to that position? Not only was Cushing a heretic on EENS, he was also a Modernist on many other fronts, a pioneer ecuмenist, religious indifferentist (I think his sister was married to a Jew), etc. So Pius XII didn't have this guy vetted for orthodoxy before appointing him to that position? That's a grave dereliction of duty. Perhaps instead of delivering 2-hour long-winded speeches to midwives and just about every other group (most of which nobody read), he could have busied himself with the selection of solidly CATHOLIC bishops?
Pius XII made Roncalli a Cardinal ... despite the file on him as being suspect of Modernism.
Pius XII also sent Montini to Milan, some claim as a punishement for outing priests behind the Iron Curtain to Stalin (who were then executed). Yeah, some punishment. But even if you don't believe that, putting Montini in Milan still got him fairly close to the papacy:
After the death of Cardinal Alfredo Ildefonso Schuster in 1954, Montini was appointed to succeed him as Archbishop of Milan, which made him the secretary of the Italian Bishops Conference. Pius XII presented the new archbishop "as his personal gift to Milan". He was consecrated bishop in Saint Peter's Basilica by Cardinal Eugène Tisserant, the Dean of the College of Cardinals, since Pius XII was severely ill.
On 12 December 1954, Pius XII delivered a radio address from his sick-bed about Montini's appointment to the crowd in St. Peter's Basilica. Both Montini and the Pope had tears in their eyes when Montini departed for his diocese with its 1,000 churches, 2,500 priests and 3,500,000 souls. On 5 January 1955, Montini formally took possession of his Cathedral of Milan. Montini settled well into his new tasks among all groups of the faithful in the city, meeting cordially with intellectuals, artists and writers
Of course, once they got Roncall in there, one of his first official acts was to elevate Montini to a Cardinal.
