Randy Larson asked if Bush will visit Israel for a week. From what I read, he will visit the Middle East for more than a week, but paragraph four of the article he linked to says:

 

The gesture is just one of several that Bush's Israeli hosts will extend to the president of their main ally during his landmark three-day visit this week -- the first by a sitting US president to Israel and the Palestinian territories in nine years.

His entire visit to the MIDDLE EAST will be longer than a week but his visit to Israel is for only three days, and that is not even a full 72 hours. According to another news item:

Bush is scheduled to depart Jerusalem on Friday for Kuwait. He will then head to Bahrain, the United Arab Emirates, Saudi Arabia and Egypt. He returns to Washington next Wednesday.
