tell that to the victims of wire fraud. they wire their savings to the scammers number, and then can't get it back, or at least, not all of it. Even after a court case.
If the other end of the wire is a bank in the USA they certainly can get it back. It's only when the money has left the country that you're in real trouble
When the money leaves the account, i.e. immediately in fraud cases.
To be clear, it's safe to assume the money's left the country in instances of wire fraud.
