Did The Second Vatican Council Ruin Everything?

There's an amorphous faction in the Catholic Church that's often called "traditionalist" that often embraces themes like more comprehensive restoration of the Latin mass, as well as less common and more extreme beliefs like sedevacantism, the view that the Holy See has been vacant since the death of Pius XII. Even if many traditionalists aren't formal sedevacantists, there's a more widespread view that Pope Francis is a heretic.

In most cases, although there doesn't seem to be a single, unifying traditionalist manifesto, the view seems to be that Vatican II represented a preemptive surrender to modernism, and a return to a single mass rite in Latin, including the Roman Canon, is the cure. (If anyone can refer me to something that might effectively summarize this set of beliefs, I'll be delighted to hear of it and pass it on.)

My impression is that many traditionalists are too young to have lived throuh the 1960s, when the Second Council took place, and haven't looked closely at the 1950s, where many of the trends that dominated the 1960s became visible.

I put together the following timeline that suggests the Second Council took place, first, in a context where Christian figures recognized cultural trends and worked to counter them well before the Council; second, that the Council was also a major response to those trends; third, that key events that define the current era took place before and during the Council; and especially fourth, that the implementation of the novus ordo mass took place only after most of the relevant events had actually occurred.

At minimum, the Council can't have caused any of the problems that traditionalsts attribute to it, as they manifested themselves either well before or during the Council.
