...eight-track tapes and Super 8 home movies do.
Never.
The anecdotal evidence is that during WWII, many young men lied about their age to get into the military right away, and soldiers often moved heaven and earth to get to the battlefield "before it was all over." Many served, and those who did not were looked down upon.
That was "a good war" and the movie propaganda was in place to make sure that everybody knew "why we fight" and wanted to go. "Destination: Tokyo." "Casablanca." "Thirty Seconds Over Tokyo." Even the postwar film "Best Years of Our Lives" suggested that despite the uprooting and devastation of war (a key character lost his hands in the war and ended up with hooks, as did the ACTOR who played him, in real life during the war), it was still "the right thing to do." When a man tells the hook-handed man that he lost his hands "for nothing, for a war we didn't belong in," that man gets decked.
Many families had men in the military. Families got used to men dying young, or coming home disabled. Other men did their duty and returned.
To some extent, veteran fathers brow-beat their sons into service in the "next war" (like Fraternity hazing, the newbies are expected to sacrifice), or sons wanted to live up TO their fathers. It was a way of life.
Then came: Korea, the fifties, Dr. Spock, the sixties, Vietnam, LBJ, the counterculture, college deferments, Nixon and Watergate, and..."the Great Divorce": the end of the draft in 1973, which severed the mainstream of American society from the military for good.
The movie business, which had once been the maker of propaganda for war, became the center of powerful anti-war filmmaking: Paths of Glory, Dr. Strangelove, Patton, MASH, Catch-22, Johnny Got His Gun, The Deer Hunter, Coming Home, Apocalypse Now, Platoon, Full Metal Jacket. Even Steven Spielberg's take on "the Good War" -- "Saving Private Ryan" -- made sure that we apreciated the savage deaths and excruciating pain of battle. Those soldiers stopped the horrors depicted in "Schindler's List," but Spielberg seemed to say: at what cost?
The "great divorce" ended the utilization of boot camp upon draftees as a behavior-modification machine that at once "made men out of boys" and sadistically bullied them, weeding out the weak with Darwinian precision before battle. Would Rush Limbaugh or Michael Moore have survived?
In the meantime, the media has done a bang-up job of giving us "warts-and-all" analysis of our leaders. It started with LBJ and Nixon, and retroactively "got" JFK, but it has kept going to the point where any parent would have to ask: sacrifice my child for THAT President?
The times changed. Its been almost two generations since the draft ended; few veteran fathers exist who CAN brow-beat their sons into service.
Everybody's wised-up and not terribly interested in the possiblity of death and sacrifice too young. The public relations effort necessary to develop support for a draft cannot exist in the current marketplace of ideas.
This is not to ignore the voluntary participation of men and women who take all of the above into account and still make the decision to serve. But COMPELLING the performance of military service?
Not in this lifetime.
