It looked just like an SLBM. The question is which nation’s sub fired that SLBM right off the southern California coastline?
There is some buzz out on the conspiracy blogs that a story will soon break about the Chinese hacking one of our own subs missiles. For example - They did hijack all internet traffic for a little while and no one knows what they did to the traffic data. Also a report unverified that a large group of our ICBM missiles went off line. Do not think that theory will work, since someone pointed out that the exhaust was too dirty. Probably not one of ours, since our missiles burn cleaner. Of course as someone pointed out on this thread, we need to examine the entire video.
North Korean?
