However you choose to look at it, military service is still widely respected as a duty to the nation and a place were patriotic sentiments exist.
I’m not debating the right or wrong of it, but it just is so. I’m pretty sure the entire history of militaries have been full of people enlisting to die and kill on behalf of some random politician they don’t necessarily agree with. There’s nothing particularly notable happening differently.
But Trump being the clown he is, this is laughable.
