I was confused by the poster's comment:

> Behind every bush is a navy seal...

Which seems to imply U.S. military personnel engaging on the ground.

No, it implies every bush could be concealing very bad news given info asymmetry.

To be fair, most actual “proxy wars” (e.g., during the Cold War) have also involved covertly-inserted forces from whichever (including both, where that was the case) of the two superpowers wasn't overtly involved.
