What do you think the doctor's thoughts about the major and the narrator are in the short story "In Another Country" by Ernest Hemingway?

The doctor of "In Another Country" realizes the narrator and especially the major do not believe his encouragements that their injuries will be healed and they will return to normal. In fact, these men are now rather detached from the war, and there is no longer anything holding them together except that they meet at the hospital in the afternoons.

As an American, the narrator has only been connected to the other men because he fought with them in the war, but now that they do not fight in the war anymore, he is detached from these men, separated by nationality and his medals. For, he has been given the medals "because I was an American," whereas the Italian soldiers demonstrated uncommon valor. 

At the hospital, the narrator and the major are put on the machines in which they have no faith, despite the pictures and the encouragement of the doctor. These machines are new and there have yet to be war injuries that prove these devices' worth, only pictures from industrial accidents that the doctor shows them. 

"One day the major said it was all nonsense." He contends that the concept of these machines has been an "idiotic idea. . . a theory, like another." Nevertheless, he comes every day to the hospital and looks stoically at the wall as the machine's straps on his once great fencing hand thump up and down on the now withered hand.

It is probably apparent to the doctor that the major is suffering within himself because he has lost his prestige as a fencer and his military position no means much since he can no longer command. One day, the major pulls his withered hand out of the machine and shouts for it to be turned off.

The major apologizes to the American, who is near him: "I am so sorry. . . My wife has just died. You must forgive me." Indeed, no machine can heal the wounds of the soul or even his hand. "I cannot resign myself," the major says of his tragedy. "I am utterly unable to resign myself."
The narrator, too, doubts whether the machines will help the major or his own injured knee. He knows he and the others "are the first to use the machines." Therefore, the photographs the doctor has hung "do not make much difference to the major," who now looks absently out the window.
