Anyone who takes DEBKA as gospel is bound to be to be disappointed.
Yes. I did a search for any story involving the Liaoning and the ONLY ONE reporting this is DEBKA.
While the US press might not report it, the UK would, as well as the Japanese. Zero, nilch, nicht, nada, null.
As some one who spent MANY years in military intelligence, I can strongly assert that this would be huge news if it was so (that the Chinese deployed the Liaoning).
Do not believe it folks, unless of course, you’re into conspiracy theories. I can’t help you with those.
