a good effort to try to bridge the remaining differences, which I believe are difficult but certainly not insurmountable.

We do everything we can to bridge the remaining differences, and try to find a solution to this. And we are very much getting the ending.

I can't say at this point how it's going to end up, ... difficult but not insurmountable.

It's not the only problem, but certainly it is a major problem.

really designed to narrow the differences and maybe, maybe even get to the point where we can really agree on something.

That's not good enough. The bridge has to be expanded.
