You can see it. Its obvious. He has no dog in this fight. Its just not his country.
My son is 17. He is forbidden to join the services until we have an American president.
You are so right and glad you told your son that. I am so happy my Daughter and son-in-law got out of the Navy over three years ago. Cannot fathom having a relative in the military right now.
You are right this is not his Country and becoming more evident by the day!
