Practically every word can be a potential dogwhistle, since provided the right context it’ll convey something that targets or marginalises a group of people. In this case because nutjobs who believe in a Jewish control conspiracy often refer to that as a “cabal”.

But that requires a context, that is simply absent from the [now deleted] comment using the word. And given a suitable context, every single word can be used to spread a hate discourse. Even a grammatical particle like “it”. (It shows how useless the concept of dogwhistles is, in comparison to looking at what the person says in a discursive level.)
