What if the United States would have written off South Vietnam as a lost cause early on in the Vietnam War and not supported it? Would the draft still be in place?
By the time of the anti-Diem coup, there were already thousands of "advisors" fighting on the side of the Vietnamese. Plus, the anti-Diem coup was largely seen as JFK's fault- a South Vietnamese collapse after that would have hurt the Democrats politically.Staying out in the 1950s in the most painless; withdrawing after the anti-Diem coup would be an easy delta as well.

How difficult would it have been to stay out after the Korean War ended in 1953? Because I've heard arguments that American entry into the Vietnam War was inevitable by the time the Korean War ended and counterarguments that Eisenhower could have just "given up" ALL OF VIETNAM and not just North Vietnam after Diem Bien Phu without a serious loss of credibility or serious political consequences.
The knock on social effects in the US would be huge.
For one thing you'd have a much less vibrant counterculture (and therefore lose the effect it had when it went mainstream in the late 70s)
I think US would draw a line somewhere else when it came to domino theory. Communist and unified Vietnam might even reinforce it with perception of communist north acting agressively. So who would US see as crucial to defend? Thailand obviously. Cambodia?
If it's earlier, it won't be by too much as Mao would probably never go for it.
Cambodia was already neutralist...
assuming the USA didn't go intervening somewhere else... the nation would be vastly better off economically, socially, morale... no vast amounts spent on propping up SV and armaments, no protests, no sense of dismal failure in the 70s. The downside would be the lack of military weaponry testing/upgrading. The war did serve as a testbed for such things as helicopters, the M16, etc, and the bugs were worked out in the field. Not to mention the development of fighter pilot skills. If the US found itself in a scrap later on, it might find itself scrambling to improve weapons and skills in a hurry...
For the USA the advantages would by far outweigh the disadvantages.
No direct involvement in Vietnam probably means more money for NASA between 1965 and 1975. Therefore: a few more Moon landings in the early 1970s; the first of 4 Skylabs launched in 1969 instead of one launched in 1973; more unmanned space probes in the 1970s including the Voyager Mars probe instead of the cheaper Viking; and the USAF Manned Orbial Laboratory, would not have been delayed and then cancelled.
Peversely no Vitenam War might mean larger American armed forces in the 1970s. So much larger that there might not be the "Reagan Buildup" of the 1980s because they were already that large.
In the case of the US Navy a force of 15 attack carries might be maintained in the 1970s instead of being run down to 12. Furthermore enough 20-knot amphibious shipping might be built to transport 1.5 or even two full Marine Expeditionary Forces instead of only one.
No Vietnam War also means a smaller national debt and less debt interest, which would pay for some of the increases in the size of the American armed forces after 1975.
If the larger American armed forces couldn't find enough volunteers then it would have to maintain the draft.

Out of curiosity, when do you see US switching to volunteer force?
Because the military technology starting to come out of the 1970s (computerization etc) meant that large conscript armies are increasingly obsolete and military forces are much more efficient when they are capital rather than labor intensive. Therefore a well educated, motivated volunteer army trumps a conscript one.
If you want an example of this, see Gulf War 1991, Saddam's mass conscript army probably would have done decently against the US if both sides used 1950s era technology, but got tore apart using 80s-90s era tech.
With early communsit victory and unified Vietnam who knows what happens. US might see Vietnam as proof of communis agressive expansion and would see Cambodia as place where it stops. Or write it and Laos off and concentrate on Thailand, but that might be problematic if almost entire SE Asia goes red.
