Quite a fine analysis.
Especially on the question of authority. Whereas His Exc. Bp. Fellay as general superior has a normal authority as superior of the pious union (pia unio) of priests and faithful, and even if one takes the SSPX as a canonical priestly association (which it is), it does not mean the possibility to exclude Bp. Williamson or other very senior priests and bishops.

The divide and conquer strategy is understood far better by the subjectivist-relativists in the Vatican, than by the bickering and (socially) outdated 'traditionalists' (i.e. the orthodox and faithful Roman Catholic priests with orthodoxy ánd orthopraxis).  

The divide and conquer worked in the Campos negotiations in 2002, and now Bp. Fellay seems to be doing nothing less. Of course I do not expect him to concelebrate the Novus Ordo as soon, but theologically and doctrinally speaking, he must do so. And Benedict XVI, just like JP 2 with Le Barroux prior Dom Gérard during his visit to hand over 70,000 signatures to 'liberate' the Traditional Roman Rite inside the Conciliar counterchurch, will not hesitate to push Fellay.

And for sure Gerhard Ludwig Mueller will not hesitate.

Even priestly ordinations may become difficult in future inside the 'regularized' Personal Prelature of Saint Pius X. Lots of conditions will be slowly imposed.

Salami tactics in order to stifle all dogmatic-doctrinal resistance and criticism.

You, Benedict XVI, Mueller and many others are intellectuals. Highly intelligent men often, highly educated (well in theology). But they adhere to modernis. They are not an average Filipino, Mexican, American or African bishop with lots of pastoral experience who just went with the flow of 'obedience'. Such later Conciliar 'bishops' can be excused (subjectively) maybe.

But the 'reconciliation' from the CDF, Ratzinger, Mueller and other Vatican view (with the exception maybe of the derailed Castrillon Hoyos - who nevertheless was a puppet), is nothing but promoting the Hegelian philosophical (and thus DOCTRINAL-DOGMATIC) synthesis by bringing the antithesis (the SSPX and 'traditionalists') into contact with the thesis (the Modernist Conciliar 'moderate evolution' neoconservative power elite of the Communio newspaper Nouvelle Théologie).

The mere attacks are from ignorant atheist journalists, ignorant ecuмenicist Protestant news followers, Jєωιѕн paranoia groups and from Hans Küng (the Concilium newspaper friend of Ratzinger, fellow theologian, but then part of the RADICALIZED Modernist 'quick quick' revolution-evolution clique). And even these attacks are not heard these last months. Lots of anti-Catholic 'intellectuals' and intelligent power brokers hope for this Fellay agreement to succeed. They know then that the SSPX and the powerful French monarchist and 'integralist' Roman Catholic resistance subculture will be watered down. They think in political terms, not in dogmatic religious terms nor in eternal salvation perspective as we (ought to) do here ourselves.

I am absolutely convinced that Archbishop Lefebvre would not have taken the 'lifting' (not an annulment, not a declaration of invalidity or practical error) of the 'excommunications' in 2009 as well as the 2007 Summorum pontificuм synthesis liturgical doublespeak (imposing the 1969 Novus Ordo Missae as 'ordinary form' of the Roman Rite of which it is a neo-Protestant hyper-liturgist neo-Modernist parody), as an excuse to give up resistance.

Every example is there. The Institute of the Good Shepherd (IBP) is crumbling due to Conciliar attempts to 'mainstream' it, into the abyss of the collapsing Conciliar structures or some neoconservative 'moderate' Modernist ecuмenist relativist network of groups like the Brothers of Saint Jean (founded by the neocon papolatry promoting late Rev. Père Philippe OP, who in fact was the one redirecting the French seminarians like now Bp. Tissier to Abp. Lefebvre in the Spring of 1969).

And after this practical compromise, doctrinal compromises will be pushed, the earthly existence and ignorant-kept parishioners and ("As long as I have the Latin Mass, I do not care about the rest") followers will lead to more 'cooperation' with Conciliar "moderate" ("conservative") doctrinal evolutionists (i.e. Modernists).

Maybe then Fr. Laguérie and Bp. Fellay can kneel down in front of the president of the Jєωιѕн Community of France to beg "forgiveness" for the (politically and practically imprudent) shelter offered to Vichy police officer and war criminal Paul Touvier (son of very pious Catholic parents and brother of pious sisters, but himself quite secularized-paganized by interbellum extremist right-wing apostate fascism-racism - like some others here too). And then the Dalai Lama and Benedict XVI can sing to Yoruba religion 'deities' together in Saint Nicolas du Chardonnet church in Paris, France. All a big happy family.

And only the exiled and banned ascetic 'fanatic' Bishop Tissier de Mallerais will be in some 'sedevacantist' small priory and barn chapel in Brittanny studying all denial of Catholic dogma in the continuing pan-religious, pan-Christian, ecuмenist-relativist-modernist 'socially conservative and moderated' Conciliar structures to which the (former) SSPX will head led by Bp. Fellay. Then in 2015 it will be like 1969 again. Barn sheds. Exiled few priests. Few if any seminaries for Tradition (apart from the Thuc line bishops who e.g. are strong in Mexico among Cristero sedevacantist descendants - 'religious fanatics' for the EU and Obama US governments of course).

This is my scenario.

But I am optimistic. God will overcome His enemies, the Holy Roman Church may seem to die, but She will never, and true Roman Catholic faithful will survive somehow (even ecclesiastical jurisdiction must survive somehow, maybe in an isolated Eastern Rite Catholic pocket in a mountain village bishop of Urmia, Iran or in Lebanon or Ethiopia - unlike sedevacantists ignoring this necessity).

And new seminarians will come, Bp. Tissier and others will build new small seminaries (maybe the - perfectly valid, 'regular line' - Thuc sede bishops may cooperate in case of sudden death of Bps. Williamson and Tissier de Mallerais?). I have seen many miracles, but I am myself unworthy, a poor sinner, intellectually lazy and very prideful, I am an orthodox Roman Catholic, but a poor sinner always practically silent in real life.....

While I am prideful, a poor sinner, disorganized, I would not mind 'going' back to the 1971 barn or shed improvised chapels in an 'underground' situation like it was before the 1980s SSPX building boom. I am young still, and never knew the 'triumphant' 1950s socially 'imposed and recommended' massive Catholicism myself. Some barn chapel in rainy Brittanny or the Vendée, with nice wooden altar and old surplices and old alb with Bp. Tissier saying the Holy Sacrifice of Mass, is not that bad. In fact, it is quite romantic for those who the history of persecution and exclusion of recusant non-juring 'reactionary' Catholics and their heroic clergy.

With regards to point #10, was Bishop de Galaretta referring to the initial preamble shown to the superiors at Albano, or was H.E. referring to the 'latest' version?

Quote

10. Bishop de Galarreta's long condemnation of the Doctrinal Preamble should silence all those who, until now have blissfully said, "but we haven't even SEEN it." An SSPX bishop has seen it, and hated it.

If + de Galarreta condemned the doctrinal preamble in Albano, the more he would oppose it now that the pope has  told them that they can: "disagree with the council, but they can not speak about the errors of the council"
Rome, in my opinion is purging the SSPX of "disobedient troublemakers" that would come to Rome with ideas of converting them.
