Bingo, I don’t believe any of the anti-Semitic stuff. He’s just grasping at straws to save his job.
"with even the government not denying that a file of the worthy officer's list of blatant anti-Semitic experiences at his comrades' hands does exist."
This effectively proves that your theory is wrong. There was a history of complaints. He did not make up the complaints after the fact as you suggest "to save his job". And, BTW, why would you say "I don't believe any of the anti-Semitic stuff?" Do you mean it didn't happen? Couldn't happen? Is there something in the story that suggests fabrication? Are border patrol agents too good to be anti-Semites? Curious to hear your theories.
