"Would you prefer to have China or Russia or the Middle East be the biggest player?"

To be fair, an objective person might prefer to have _no_ "big players"

Whether a biased or self-interested commenter on the subject believes this is possible or not doesn't eliminate the possibilty of this preference

It is like asking whether a voter would prefer to have the "biggest players" giving funds to X candidate or Y candidate, ignoring whether the voter would actually prefer campaign finance reform instead

You're not wrong, but youre showing an unserious idealism yourself. Your scenario is more akin to "i dont think there should be a biggest nuke owner, so we're going to pass laws banning nukes" While the USSR simply proceeds with making nukes.
