Veterans were almost always portrayed in a positive light
Rebuilding the military was a primary focus in the 80s, and media and entertainment came around on that. Instead of the gloom of 'First Blood' and 'Deer Hunter', pro-military movies like “Top Gun” (1986) became the norm. Having been commissioned as an Infantry Officer in 1990, and deploying to the Middle East throughout the 1990s, I experienced the complete turnaround in treatment of the military by society. Returning from deployments in uniform meant the constant refrain of “thank you for your service” versus the distain many Vietnam veterans experienced.
Veterans were almost always portrayed in a positive light. The nation seemed to go overboard in thanking veterans, and I suspect it was partly to make up for treatment of Vietnam veterans. Veterans Day became a more important Holiday beyond the military. Americans realized World War II veterans were a particularly important group to honor before they were gone.
During the post 9-11 wars in Iraq and Afghanistan, America continued the laudatory treatment of the military and veterans. I can still remember returning from Afghanistan in fatigue uniform and the airport loudspeaker announcing our return to cheers of civilians. Most younger Americans by then had grown up without the memory of the post-Vietnam treatment of veterans. During this period, World War II veterans were dying at thousands per day. 'Honor Flight', flying World War II (and later Korea) veterans to Washington DC to see the World War II Memorial, came into being to specially honor those veterans.
