Crewed vs uncrewed is a decision made at the very beginning of the planning stages, years ago. These days a crew is just a gigantic extra expense on a mission with little return. Remotely operated missions can achieve all their scientific objectives.

Manned lunar lander is a mich complex piece of technology which needs to be developed from scratch. It also needs a much more powerful rocket which Russia don't have either. It's at least a decade of extra R&D time even if they get all the funding they need and magically get rid of corruption (which obviously won't happen).

It's unmanned not because they chose it but because they are literally incapable of making a manned mission (at the very least for a couple of generations).

What? It clearly states in the article they knew it was risky... I would consider that rushing.

That is what they said, yeah.
