It’s because he has no respect or reverence for anyone else but himself. He’s doing the thumbs up because its about him and doing a photo op. These dead soldiers are literally being used as political props.
It’s sick. It’s just another example of the complete lack of respect and understanding of people who serve in the military, from the “suckers and losers” to “I prefer people who weren’t POWs” to “the Medal of Freedom is actually better than the Medal of Honor”.
Any vet not completely brainwashed into the cult should be outraged.
PS
I would $1000 to see three or four Marines in dress blues remove Trump from the cemetery.
