Speaking to Al Jazeera's David Chater in Ramallah on Wednesday, Khaleel Shaheen, a Palestinian political analyst, said: "For Palestinians the visit will not add anything new. The Americans have red lines that they cannot cross in their relations with Israel.
"This line permits Israel to continue its settlement activities and its aggression against the Palestinians in the West Bank and the Gaza Strip.
"The Palestinians do not expect much from this visit. People here are worried more about the roads that are going to be closed tomorrow rather than worrying about the content of this visit.
"This visit will give a push for both the Israeli prime minister and Palestinian president Mahmoud Abbas. Both leaders are both weak. We should know that Olmert is facing a hard time and needs this visit to strengthen his situation.
"Abbas also needs this visit in order to convince the Palestinians that there is something going on. At least there is contact with the Israelis.
"But we should notice that the Palestinians weakened their position by themselves. They chose to continue these negotiations, while Israel is continuing to build settlements.
"This is something comes in contradiction with the Palestinian stance and against the promise given to Palestinian people that there would be no negotiations as settlement activities going on."
Too little, too late
On the Israeli side, Yossi Beilin, a Knesset member, told Al Jazeera's Jacky Rowland in West Jerusalem: "I do not think that President Bush is coming to solve any problem.
"In my view, I think what he is coming to do is to tell the world and tell us - the Palestinians and Israelis - that he cares, that he believes in the last year of his second term, there is a chance to make peace and to sign a peace treaty.
"This is of some importance after seven years in power, in which he did too little for the peace process in the Middle East.
