Maybe I'm reading the situation wrongly but I believe that PM Olmert is not interested in his just remaining at the helm of the current Israeli government. Olmert is genuinely keen on reaching an agreement with the Palestinians based on the already revealed Israeli stance on the core issues (Haim Ramon) discussed through media reports. There's no doubt that Olmert is challenged by members of his coalition but really at the end of the day, they'll have to conform to U.S. pressure. Unfortunately, the PA is not ready to control the security situation and this is the main stumbling block, hence, unable to announce timelines, commitments,etc. But I'm pretty convinced that PM Ehud Olmert is able to reach a peace agreement very soon and is doing the best he can with all the interferring variables concerned.
