These are the kind of stories that i like the least, each time someone writes the Foundation as a subservient organisation to the military of one country they end looking extremely weak.
Specially one you remember that they have to deal with monsters like The Global Occult Coalition; The Serpent's Hand; Sarkic Cults; The Church of the Broken God; Anderson Robotics; Marshall, Carter, and Dark Ltd; The Three Moons Initiative, etc.
And then you have the Foundation bending the knee to the US military, despite any of the above mentioned groups being able to go and control the US whenever they want.
