Red Rogue
True story about how a faction within the Kremlin, headed by Mikhail Suslov and Yuri Andropov, tried to trick the USA into a massive nuclear attack on Red China in 1968 by disguising an old Russian missile sub as a new Chinese missile sub based on the plans of the old Russian model, and hitting Pearl Harbor and the city of Honolulu with a megaton range nuke missile.

The plot failed because the plotters, including the covert ops team that was sent to join the sub crew at the last minute to take it over at the critical moment, did not know about a secret device the Russian nuclear weapons command had built into their missiles to guard against a sub commander going rogue and launching anuke attack on his own.
I'm at the part where we know all these details because the sub, which sank when the secret device blew uo the (non-nuclear) fuel in the missile and blasted a hole in the sub, was later salvaged by the US secret salvage ship the Glomar Explorer, which of course, as of 2006, has long since ceased to be secret.
Fascinating read!
I'm also into the first book of a scifi trilogy by David Weber where the moon turns out to be a disguised alien warship 3000 miles in diameter which has been there, having replaced the moon and sent it into the sun, for about 52,000 years.
Hey! It could happen! (Yeah, right!)
