Yup. He should NOT attend the funeral. He should go and meet with the parents in private at a hotel. He should listen, and console, and explain if he comes, his presence will detract from the ceremony for the slain honored son. Give them as much time in private as they wish to consume, then invite the family back after. He should say nothing to the eneMedia except for his sorrow for the hero son. Nothing.
I understand your take, I truly do. This is a very tough call.
The grieving Momma Bear has reached out, in her time of need, in her desperate desire to make some sense of her loss. She seeks comfort from someone strong and compassionate.
Momma Bear observed, she learned and she now believes under different leadership her loss was largely avoidable. She has calculated under a different sequence, under a different approach and under a real leader, her circumstance may be different.
As I do, I imagine she believes President Trump is loving, he is kind and his presence would aid her.
Above all, President Trump will quietly do the right thing for this Marine Mother.
I bet my life on it.
