The ending reveal doesn't even fit neatly into the hot-button American political issue you're associating it with. The film is clearly trying to make the viewer work out their view on the issue, and I think the film takes essentially no stance (unless you think that not taking a strong stance in one direction constitutes endorsement of a different direction).

Some might even say the film lacks courage, both by taking no stance on the issue and by presenting a scenario that only vaguely matches the hot-button American political issue.
