Not really, this would be a slam dunk defamation case even in the US. The diver isn't a public figure who was called a pedophile in public by one of the most famous people in the world. Not to mention, libel laws are much stronger in the UK than they are US. (i assume he would be suing in a UK court because of the more favorable laws so long as he is still a UK citizen)

He'd be able to collect like 5x the damages in a US court than anywhere else in the world. US system has way higher payouts for this kind of nonsense.
