Gravity assist has been used by space craft long before Voyager and has continuously been used since.

Do you mean alignment of the outer planets for the grand tour? If it happened in 5 years, we'd miss it. It took over a decade to assemble and launch the Voyager probes.

5 years was just something close enough that tech wouldn't advance too so it would still mostly be the same

Propulsion technology doesn't advance that fast, assuming more or less present day stuff 10 or 20 years out is fine

As in doing a similar grand tour? For Jupiter & Saturn, it feels especially silly since they have already had orbiter follow-up missions (Galileo & Juno for Jupiter, Cassini for Saturn).

In the cases of Uranus and Neptune, a lot of the mission proposals (including the planetary decadal survey are also for orbiters rather than flybys. Trident is something of an exception.

What about China, India, UAE they didn't send anything to out there?

They've done various Moon and/or Mars missions, but nothing to the outer solar system.
