Usually from stories like these:
The United States, Israel's main ally, had initially been expected to voted in line with the other 14 but Rice later became the sole abstention.
"In the night between Thursday and Friday, when the secretary of state wanted to lead the vote on a ceasefire at the Security Council, we did not want her to vote in favour," Olmert said.
"I said 'get me President Bush on the phone'. They said he was in the middle of giving a speech in Philadelphia. I said I didn't care. 'I need to talk to him now'. He got off the podium and spoke to me.
"I told him the United States could not vote in favour. It cannot vote in favour of such a resolution. He immediately called the secretary of state and told her not to vote in favour."
