IMO UN resolution votes should be secret ballot.

Each country can choose (and replace) their own representative, but once the choice is made, what the representative does is up to their own conscience.

Less "pressuring" by great powers, more seeing how people really think.

More generally, perhaps a core theme of the next wave of democracy will be less "transparency and accountability" and more deliberate indirection and room for (pluralistic, aggregated) individual conscience.

(this applies to DAOs too; eg. see NounsDAO https://aztec.network/blog/nounsdao-private-voting-final-update)

you also need a secure and audited environment (physical booth?)
collusion and bribes will still happen - outcome based
representatives are unelected - presidents/PMs have foreing affairs power
