Despite the author's protestations of this-is-not-conspiracy-theory, it is a conspiracy theory. The pull quotes include one beginning with: "I’m just asking, Is it a complete coincidence ...". Ah, yes, the old favorite of Qanons everywhere, "I'm just asking".

This is just another attempt to cause a significant fraction of the population to throw up their hands in resignation, and excuse everyone in the USA from responsibility.
