I was thinking the Hunt for Red October might be referring to Comey, if not Mueller, or perhaps both.
Read Comey's tweets, they're all very oblique – Thats it? Maybe he was actually hoping for more to be released. He had another tweet about the FBI speaking up, which also coincided with news reports of the whistleblower talking about off-site "secret society" meetings. He's also tweeted about justice being served eventually, even if it takes a while. People assumed it was about Trump and Mueller, but I think Comey is pulling a Trump and using confirmation bias – people hear what they want to hear because he phrases things ambiguously.
The fact that he's going to be teaching ethical leadership despite demonstrably having broken the law (leaks, perjury) makes me think he may have immunity - why else would anyone hire him?.
Trey Gowdy also made a comment after his testimony a while back to the effect that history would look back at Comey in a better light.
He's been a swamp creature for the Clinton's for decades. If he turned, it would be huge.
Or I could totally be wrong, and it's about Kim Jong Un himself defecting from NK - things got mighty quiet after reaching a significant fevered pitch with nuke launches. Maybe it's the Olympics, maybe not.
