If they infiltrated and took over the mainstream Church even to the level of the papacy, don't you think they would try to infiltrate the resistance?
You can't just randomly extend lines or take mental shortcuts. It doesn't work that way.
Why infiltrate a microscopic group? Who cares about such a small group? Even if they maintain the true Catholic faith, 99.999% of the country won't have access to one of these chapels, so it's still Mission Accomplished for the destroyers. It's like saying the Germans aren't just blowing up shipping in the Atlantic, but they are spending thousands of man-hours scouring every square-foot of the ocean looking for 4-man rubber lifeboats as well.
A) a tiny group is much more close-knit and hard to infiltrate. Everyone knows everyone. B) the payoff is not worth it, because even if you gained full control of the group, it's insignificant.
The SSPX is a large group. They got influenced, taken over, or whatever but only AFTER they became a huge, influential organization -- probably over 80% of the whole Trad movement as measured in Trad population, # of priests, real estate, etc.
Even more so the Catholic Church -- about 10,000X the SSPX. They even have the official title "Catholic Church" and the global prestige associated with the Pope.
You need to put down AA-1025. Even if that book were 100% true, it only spoke about a broad plot to infiltrate *the entire Catholic Church* pre-Vatican II. When there are thousands of seminaries worldwide, each with HUNDREDS of seminarians, it's much easier to infiltrate a bunch of plants. It's like trying to shoplift a Wal-mart vs. trying to shoplift a small jewelry store where the one employee is pretty much constantly watching you.
History doesn't repeat that way, silly. If it did, then any 80 IQ normie would be a wise genius. No, it's always a bit different. Things are more complex than that. History might rhyme, but it never repeats exactly.
