Having tracked down the article it does not seem to be a rebuttal at all about the truth of the story - merely claiming at one point that it is “not supported by evidence”, as if any such story ever is. The rest seem to be a set of quibbles over whether only the 4 x F-35Bs which have arrived in the UK can count as being “delivered”, the number of US carriers actually currently with air wings embarked etc etc - none of which really impact on the story.
The rest being a general bitch and moan about the way the press report such things rather than printing “good news” stories about the forces - as if there was much good news to print.
And of course a good sulk about why, If originally proposed, the decision was made to cancel, with 3 paragraphs about why Trump would not find such a visit frustrating and a very positive message about the ship could have been delivered.
So so rather thanseeing of a rebuttal of the story as printed, I see it more as a defensive rebuttal of the reason given for cancellation.
