I am implying that the leaks are coming from the other end of the line, the end we cannot control.
Trump is a populist, so generally speaking most of the rest of the world hates him. They'd be predisposed to make him look stupid with our media only too willing to help.
Except the leaks have come from three unique phone conversations to different leaders. And while both parties have said they are fake, what they did confirm shows there was a grain of truth to the leaks. They did say, for example, Trump talked about 'bad hombres' and offered help, just not the sending troops part. You have a similar situation with the AU leak. Someone is privy to part of the conversation or the gist of it, and the common factor is the WH.
