What is the major source of the conflict between Krebs and his mother in "Soldier's

Home"?

The major source of the conflict between Krebs and his mother in "Soldier's Home" is that Krebs is not able to connect with people.

Explanation:

'Soldier's Home' by 'Ernest Hemingway' is a story about a soldier 'Krebs' who returned from World War I to his original life. He wanted to share his war experience with others, but he is not able to do so because there is a disconnect between him and other people. As Krebs had seen lot of deaths and suffering, there was a feeling of fear and isolation in him. He did not want to get into a relationship with any girl.

Also, Krebs did not believe in God anymore, nor does his pray with his mother. So, he even decided to leave his home as the trauma of war had changed him a lot and he couldn't connect with people. This creates a conflict between Krebs and his mother.
