Like balancing whose interests?

I'm thinking you're meaning like "politics is about trying to understand/impact what could plausibly occur", whereas the "truth" you mention is inherantly unconcerned with that, but I think there's also value in finding and debating it.

What's implementation without a target? Is politics concerned with improving conditions for people, or is it just balancing enough interests that we don't start killing eachother?

It's shades of both I think, and there's fierce disagreement about both the global optimum and how to or if it's worth getting there
