Veterans (including wounded and KIA) are props for campaign videos and posters, backdrops for rallies, staged aircraft carrier landings (OK, those guys were active duty but same concept) and generally to be exploited for political purposes. When Trump says "our veterans" he means "my campaign props." That's it.

Trump likes thugs, strongmen and murderers; this has been well established. But his impending pardons for Americans who were convicted or accused of war crimes while serving in the US military is a signal that anything goes for those in service to TRUMP, which is how he views US military forces. They're HIS forces- remember all his comments about "my Generals?"

He's planning on becoming a real out-in-the-open dictator. I am sure of it. This is an attempt to engender blind loyalty to TRUMP among military personnel- something all dictators need.
