When Ehud Barak said in his press conference that the demand for Olmert to remove himself is not immediate, as he understands Kadima needs time to figure out what to do and how to do it, what did he mean?

Barak clearly did not give a definative ultimatum. Was he saying they have time to work out the issue, and if they need that time, be it a few weeks or a month or two, they will have it, as long as they begin the process? Or did he mean he will wait a few months regardless of whether Kadima gets moving or not?

I wonder, because Ehud Olmert responded by saying he is not going anywhere.

So with Barak's demand being rejected, will Barak give Kadima a few months anyway, or will he now force elections because his leeway was only to give them time to work out the issues, but if they are not using it for that then there is nothing to wait for?
