You got me to look into this further. I was seeing if there was a backdoor - and it appears there isn't. https://signal.org/blog/there-is-no-whatsapp-backdoor/

Given that I don't see why more of us Americans aren't using WhatsApp! :)

Ofcourse WhatsApp is not open source, as opposed to Signal (the app). You can never be truly sure if the protocol is implemented without backdoors because you can't verify the code. But I agree, WhatsApp is a pretty solid app.
