"My point is that you can't converse with many controllers"

I assume you mean, foreign pilots instead of communicate with controllers.
Most "over the ocean" controllers are U.S. Citizens, but I'd agree about SOME of the foreign pilots, maybe 30 percent.

Now in the pilot's situation, I have NO COMPREHENSION of what it's like to try to focus your concentration after a 13 hour flight, or in their case with tailwinds helping you, maybe an 11 hour flight.

The guy sitting in the tower in Buenos Aires or Sao Paulo will speak Spanish or “Portagee”, Pilots rarely converse with pilots of other flights. “Over the ocean” controllers? Yes, Oakland Oceanic Control covers a vast part of the Pacific but when you approach Japan you are talking to Fukuoka Control and he is a Japanese with limited English skills. Have you been there? I have. Also, I have flown 25 hour flights with 2 air to air refuelings..I know what tired is. Of course I was in my 20’s then.
