Obama has indicated that he is pretty unreservedly pro-Israel. There's nothing in that interview to suggest that his position is any different from that of Clinton, McCain, or Bush for that matter.

Which is not particularly surprising in anyone running for President in the USA. Basically candidates are treading water on this issue, and always will.

It seems to me that it would be better if more attention in discussions like this could be directed to ideas about ways in which things could be made better, or threaten to be made worse, rather than going over the terrible injustices of the past.

That's not to dismiss the importance of exploring the past, but there are ways of doing that which have more potential of getting somewhere useful. I remember coming across an article once about technique of conflict resolution based on the principle that each side has to be able to state the other sides position in a way that satisfies the other side as being fair, accurate and dispassionate.
