I don't think there is evidence of all that he hopes in his post, but China has already conducted military exercises in Canada, the country run by Fidel Castro's son. China already operates in our hemisphere from spying on our nuclear subs in the Caribbean to fishing fleets in South America. They also routinely send us massive numbers of cargo containers. I don't think there is an imminent invasion plan, that's a huge risky move and they seem methodical and patient.

As for mil coups, before the first they sound preposterous, but there have been so many in history it wouldn't be a total shock.
