Hmm. This is a very intriguing item. Thanks very much for posting it.
I figure it’s the Chinese flexing their muscles in desperation over our devaluing the dollar. When this administration finally collapses the dollar it’ll be bad for Americans but it’ll be worse for the Chinese because we can then repay them with Monopoly money. After all their boasting about owning our debt and our being so indebted to them - it’s like WE now have them on OUR leash. They want to call in our debt ? OK , we’ll just print up some more. Our debt used to be a large part of their economic strength. Ooops ! Sorry ‘bout that. (And - Nobody in our military wants to admit the Chinese could sneak a sub in that close.)
