Nuclear winter isn't triggered directly by the nuclear bombs, but rather by the cities burning in the aftermath. A large number of firestorms would propel tonnes of soot into the stratosphere, which would block enough sunlight to create a massive, year-round winter. Then, once there's snow everywhere, Earth's albedo would be high enough to prevent future warming, basically locking Earth into an ice age until natural variance pulled us out again (typically estimated on a timescale of 10,000 years).
Considering the trailer didn't show any of those effects, I think we can rule out nuclear winter.
There might have been a short nuclear winter...followed by rapid return to greenhouse effects.
Probably the combo of climate effects from
1. normal fossil fuel produced greenhouse gasses
2. short nuclear winter
3. different intentional geoengineering attempts to deal with the above (all that end up causing more problems)
gives some type of a climate whiplash
In combination with the setbacks to the global economy from a small nuclear war
Might be enough
I think however that throwing in
a computer virus that destroys the global nature of the internet (and costs a lot in the meantime)
and
some failure of the green revolution (modern crops die out...food prices spike destroying the global economy for a long time period)
