I guess they can either 1) dig themselves deeper into a hole and issue another round of QE to inject liquidity into the markets or 2) do absolutely nothing. Though they are probably loathe to do nothing as then it would seem like they don't have a solution.
Whatever happens, it will be an interesting/exciting time in non-traditional monetary policy that will generate a ton of academic papers going forward.
That's not something the Fed can do.
That's something Congress can (in theory) do, but hasn't shown much interest in doing.

I don't think anyone has a preference for monetary stimulus so much as the fact that the only place where there are sufficient people with interest in stimulus to effect anything is at the Fed, where the only lever they have is monetary stimulus.
