Just a day after a Palestinian terrorist rammed his bulldozer onto a busy Jerusalem street injuring 18 people, U.S. Presidential Candidate, Barack Obama, arrived to Israel for a brief but meaningful visit.Both Israelis and Palestinians are closely watching Obama's every move, as both sides seek to clarify the stance of the U.S. presidential candidate on key issues in the region. Obama attracted attention in June when he told a pro-Israeli lobby group that Jerusalem must remain Israel's undivided capital - only to amend his stance on the issue the next day. 07/23/08
