What is the problem with the current approach to negotiations with Russia regarding Ukraine?

According to Ambassador McFaul, the current issue is that the US is essentially 'negotiating with ourselves' by considering lifting sanctions without requiring Russia to make any concessions. He argues that Russia is simply waiting for the US to give more while not offering anything in return. McFaul emphasizes that for meaningful progress, there needs to be a fundamental change in approach. Russia must be clearly told what they need to do and what they need to concede in negotiations, rather than the US making unilateral concessions. This one-sided approach undermines the effectiveness of diplomatic efforts to resolve the Ukraine conflict.
