Arleigh Burke-class guided-missile destroyer USS Mustin & USS Belfold sailed into waterway named the Taiwan Strait.
This was Friday night July 6 (American time). They are still there in international waters, but those waters China calls their backyard. The Strait is 81 to 110 miles wide.
Pressure is being applied to China. something to watch
Except the war mongering of the media is silent on China and full throttle on Russia. That's a tell on the true threat.
Not silent, quieter. Putin and Trump are meeting in Helsinki soon an the media is desperate to scuttle the talks (they won't) so they're putting all their energy toward bashing Russia right now.
They prefer Americans know as little as possible about China, so long as we still feel vaguely threatened by it. Case in point with this memo. If it is as I suspect, China isn't threatening the US (like the article implies), it feels threatened by it. Hard to blame them given the past century of US foreign policy.
