I sincerely believe that the following happend --
Masons/Communists/Modernists had been infiltrating the hierarchy for decades and even centuries prior to Vatican II. In the 1958 Conclave, Cardinal Siri was elected, but the Communists/Masons forced him to step down. Then they installed their agent Roncalli in his place, the "uncanonically elected" pope described by a prophesy of St. Francis. Once the smoking gun proof for this comes to light, then we'll have our ring.
Then the Church will need to revisit the ecclesiological debates between R&R and the sedevacantists and settle those disputes as a matter of principle.
