Never heard of it until I read this here:
Not only Cronkite and Rather participated in this appalling exercise [to defend the Warren Commission], so too did Eric Sevareid, appearing at the end of the last show and saying that there are always those who believe in conspiracies, whether it be about Yalta, China or Pearl Harbor. He then poured it on by saying some people still think Hitler is alive and concluding that it would be impossible to cover up the assassination of a President.
The Pearl Harbor conspiracy theory is pretty well known, but what is the one about the Yalta Conference? Or China for that matter? This is circa 1975.
I can totally see QAnon bringing this one back. They'll believe anything about "Commiefornia".
They did but it was coming north from Canada iirc, something about a bunker with 30,000 chinese troops being blown up

Conservative dipshits look at a map challenge (impossible)
Did the Chinese soldiers get up there through one of their many holes dug straight through the earth
Me and 49,999 of my comrades vibing in the Brotherhood of Nod subterranean APC on our way to invade America. Not a phone in sight, just dudes living in the moment.
I was actually half expecting somebody to say they've heard the same thing on fox news last week.
