That was Sun Yat San ~ he was literally called from a conference in St. Lous to go to China to be the interim President. The old regime simultaneously lost the mandate of heaven.
Doesn't mean much to us, but those ol'boys are still into PORTENTS and SIGNS. They read them like some here do polls.
So Obama launched the B2s to near China and over Korea and that's a portent sufficient for the Chicoms to send a hunk off their ground army up on the Yalu.
Un's Confucian advisors (the military is still operated along the lines of the ancient yangban system) are probably jumping out of their skins over that fly by.
If that's the portent meaning Un's regime has lost the mandate of heaven, then they'll be wanting to escape to China. If the Chicoms hear that sort of nonsense spreading into the Northern cities of China, they'll be wanting to prevent escapes from Korea.
Obama and his running dog lackeys know none of this ~ and probably haven't been listening to their East Asian analysts.
Who knows. The only thing I am sure of is that several people from that area all reported lots of activity at the same time.
