In the US at least, the end of the Vietnam war didn't have the same social attitude as the end of WWII.
For one thing, there wasn't really the same largely positive attitude of we're glad it's over but it was super important that we were there. There wasn't much of a hero's welcome for returning soldiers from Vietnam.
Not to be overly morose, but the casualty rates for US soldiers was much lower in Vietnam, so there was less of an urge to make a big family to make of for the loss of others.
Afghanistan/Iraq were even less so.
WWII was an amazing boost to the whole US economy, and there was a big post war boom, from reconstruction, and other things. That didn't really happen for Vietnam or Afghanistan/Iraq.
Now, if we have another total war, and come out on top, I would expect another baby boom. Even if we didn't come out on top, if post-war reconstruction enabled a good economy, we could still have a boom.
