Reuters) - President Barack Obama reassured Jewish donors on Monday he strongly supports Israel, stressing close ties between the United States and the Jewish state, but also emphasizing that changes in the Middle East will require a fresh look at the region. "Both the United States and Israel are going to have to look at this new landscape with fresh eyes. It's not going to be sufficient for us just to keep on doing the same things," Obama said at the first of two big-ticket fund-raisers where he was speaking on Monday evening.
