The story behind the story of Dr. Skousen is very interesting and I hope will be of some benefit to others. It goes like this:
Dr. Skousen is an avid reader of the Book of Mormon. He read in 3 Nephi chapter 16 and 21 wherein the Savior says that if the Gentiles of the last days don't repent of their sins, among them being the sin of upholding secret combinations, then the remnant of the land, consisting of the lamanites, will go through the Gentiles as a lion among the beasts of the forest and they will destroy the Gentiles. But if they repent, that won't happen.
Well, Dr. Skousen composed a talk about the subject and began telling that talk about how the Lamanites and their cousins, the Mexicans, would come among the Gentiles and destroy them in the last days. And of course, with the talk among Mexican-Americans going around that they say they are going to reclaim southwest America, and call it "Aztlan," there seems to be a lot of evidence that that could happen.
Dr. Skousen told my friend that one day he heard that a General Authority had heard his talk and began using that talk himself. Who he was Dr. Skousen never said. But this GA gave that talk a lot for awhile. Then, according to Dr. Skousen, President Hinckley told the GA not to give that talk anymore because that's not the scenario that will play out. President Hinckley told Dr. Skousen that he should go back and read the part in 3 Nephi 21:22 which says, "But if they will repent and hearken unto my words, and harden not their hearts...." then, to summarize, the scenario about the remnant of Jacob going through and destroying them won't happen.
So Dr. Skousen asked President Hinckley, "What will make the gentiles repent?" And President Hinckley replied, "A plague." He was told to go home and read about the plague in Section 29 of the D&C, verses 18 and 19. Then he said, read D&C 112:24-26 about how the plague shall start. Dr. Skousen firmly believed that America would never be invaded from without
