Just to let you know what's going on:
President Trump has telephoned the Chinese leadership over North Korea. We don't know the contents of the call. Here's what we do know:
There's a US Navy strike force on its way to the Western Pacific. North Korea has promised nuclear retaliation for a show of force.
China stopped importing North Korean coal last week. That represents a major chunk of North Korea's exports.
China now has 150,000 troops on the North Korean border.
North Korea has promised something big on an annual national celebration called Day of the Sun, coming up this month.
And last but Way Not Least:
North Korea has ordered the immediate evacuation of about a quarter of Pyongyang's population. Foreign reporters have been told not to bring cellphones.
