I agree with you that the potential fall of America is the context of the song.
However, the line “Do you recall what was revealed” points to content rather than context. That is, it asks for something specific.
Was McLean was thinking of the cabal and their satanic rituals when he wrote that line? At first I thought he probably wasn’t.
But...he would probably have been aware of JFK’s Secret Society speech. And he likely put careful and extensive thought into the whole scenario of what Waylon did.
And it should be emphasized that the keystone for the cabal, the deep state and their stupid world order—the thing that holds it all together—is secrecy.
When their secrecy dies, they die.
It’s the same thing for Soros-funded information sources, including moles posting on FreeRepublic.
Imagine if these moles could only post in red here. We would know to skip over their posts. They’d be zotted in seconds.
