It's a major subject of debate. You can see a blatant and open hostility shown towards soldiers coming back from Vietnam but then also see soldiers be welcomed with block parties when they return from the Middle East.

Both of these conflicts are almost universally frowned upon by the American public but the soldiers from one are treated with far more respect as a general rule of thumb. Granted, many Americans look back on our treatment if Vietnam vets with a good deal of shame as well.

I'd say it came some time after Armistace Day was made a national holiday. Prior to that, military service appeared to be seen as a not too remarkable thing to do. Not frowned upon of course but not really glorified either. Glorified may be the wrong word and I'll replace when I think of a better.

But Armistace Day really served to put a spotlight on the sacrifices that are often required from soldiers in times of war and I think that's what really got the ball rolling and it never really stopped.
