From your own source:

> Joint Chiefs Chairman Gen. Dan Caine has been advising President Trump and top officials that a military campaign against Iran could carry significant risks, in particular the possibility of becoming entangled in a prolonged conflict, according to two sources with knowledge of those internal discussions.

"that a military campaign against Iran could carry significant risks, "

specifically

"could carry"

Sounds like people doing their job, and informing a president of potential outcomes, precisely what I predicted above. The media always makes things seem more adversarial than what it turns out to be.
