How to understand 委ねる in this line


I'm failing to understand what it means for the 戦い to 委ねる in the below
sentence. Is there anyone who could clarify what it means in this case?

> この戦いは国の勝ち負けだけじゃなく一人一人がどちらを選ぶのか **委ねている**

Additional context:

The country is currently in a state of internal conflict, with one faction
looking to split off (due to the corruption in the country) and become their
own independent state.

The protagonist is currently taking part in this battle,, but not because they
care about the state of the country. They instead want to get revenge on the
leader of those looking to make an independent state because he killed someone
close to her.

The line above was said by someone who previously fighting alongside the
protagonist but joined the other side. They are trying to convince the
protagonist to stop seeking revenge, and to join their side.




I think you might be having problems because you're assuming the は is marking
the subject when it's actually marking the direct object. That is, it's
replacing a を. (See also [this
question](https://japanese.stackexchange.com/questions/49081/the-difference-
between-%e3%81%af-and-%e3%82%92).)

Working out from the middle:

> 一人一人がどちらを選ぶのか

This is an embedded question acting like a noun phase. (See [this
question](https://japanese.stackexchange.com/questions/13034/usage-
of-%E3%81%8B-after-a-clause) ) meaning "which one each person chooses."
Normally as the indirect object it would take a に afterward, but nominalizing
questions in this way usually deletes the を/が/に.

> 国の勝ち負けだけじゃかく

"not only the victory/defeat of countries", i.e. the outcome of the war
between the old country and the rebel country

> この戦い

the fight (for independence)

> 委ねている

委ねる{ゆだねる} generally means to completely entrust something. That action
requires three things: the actor/subject, the trustee/indirect object, and the
object entrusted. There are only two of those in this sentence though: the
object (the fight for independence) and the trustee (that giant composite
thing between は and 委ねる). You'd have to infer the subject from context, but
given the speaker I'm betting it's something like "we" or "the rebellion".

All together and smoothed out a bit:

> "We're entrusting this fight (for independence) not only to the
> (battlefield) victory of our country, but also to which country each
> individual person chooses."

I think the speaker is trying to convince the protagonist that their decision
of which country to support is significant—they can't say that what side they
support doesn't matter and they're only in it for personal reasons, because
the rebellion's success relies on individuals' decisions just like his.
Deliberately, even, because its success is being partly entrusted to such
decisions.

Edit: added ref for は replacing を
