"The understanding between the US & Israel was to oppose settlements formally but not evolve this a fundamental disagreement.."

buying into "Obama wants to finish Netanyahu", ....STRATFOR, excerpts:

"Amid the rhetoric of U.S. President Barack Obama’s speech June 4 in Cairo, there was one substantial indication of change, not in the U.S. relationship to the Islamic world but in the U.S. relationship to Israel. This shift actually emerged prior to the speech, and the speech merely touched on it. But it is not a minor change and it must not be underestimated. It has every opportunity of growing into a major breach between Israel and the United States.

The immediate issue concerns Israeli settlements on the West Bank. The United States has long expressed opposition to increasing settlements but has not moved much beyond rhetoric. Certainly the continued expansion and development of new settlements on the West Bank did not cause prior administrations to shift their policies toward Israel. And while the Israelis have occasionally modified their policies, they have continued to build settlements. The basic understanding between the two sides has been that the United States would oppose settlements formally but that this would not evolve into a fundamental disagreement....

Obama has positioned the settlement issue in such a way that it would be difficult for him to back down. ...What Obama has done is restated formal U.S. policy, on which there are prior Israeli agreements, and demanded Israeli compliance. Given his initiative in the Islamic world, Obama, having elevated the issue to this level, is going to have problems backing off.

........Unlike Ariel Sharon, a man of the right who was politically powerful, Netanyahu is a man of the right who is politically weak. Netanyahu gave all he could give on this issue when he said there would be no new settlements created. Netanyahu doesn’t have the political ability to give Obama what he is demanding. ....

Therefore, Obama has decided to create a crisis with Israel. He has chosen a subject on which Republican and Democratic administrations have had the same formal position. He has also picked a subject that does not affect Israeli national security in any immediate sense (he has not made demands for changes of policy toward Gaza, for example). Obama struck at an issue where he had precedent on his side, and where Israel’s immediate safety is not at stake. He also picked an issue on which he would have substantial support in the United States, and he has done this to have a symbolic showdown with Israel. The more Netanyahu resists, the more Obama gets what he wants.

...... If Obama can force Netanyahu to concede on the settlements issue, then he will break the back of the Israeli right and open the door to a rightist-negotiated settlement of the two-state solution.

In the course of all of this, Obama is opening doors in the Islamic world a little wider by demonstrating that the United States is prepared to force Israel to make concessions. By subtext, he wants to drive home the idea that Israel does not control U.S. policy but that, in fact, Israel and the United States are two separate countries with different and sometimes conflicting views. Obama wouldn’t mind an open battle on the settlements one bit.... This is not a subject around which Israel’s supporters are going to rally very intensely, in large part because there is substantial support for a two-state solution and very little understanding or sympathy for the historic claim of Jews to Judea and Samaria....

Thus, the question is what Netanyahu is going to do. ..... That’s where Obama is going to have to make his decision. He has elevated the issue to the forefront of U.S.-Israeli relations. .....when he raised this issue and knew perfectly well that Netanyahu couldn’t make concessions on it, so he had to have known that he was going to come to this point. Obviously, he could have made this confrontation as a part of his initiative to the Islamic world. But it is unlikely that he saw that initiative as ending with the speech, and he understands that, for the Islamic world, his relation to Israel is important. Even Islamic countries not warmly inclined toward Palestinians, like Jordan or Egypt, don’t want the United States to back off on this issue....

.....over the past generation, Israel has moved from a dependent relationship with the United States to one of mutual dependence.(IS THAT SO?).... and from this point of view follows the idea that he (Netanyahu) might simply say no to the United States on the settlements issue and live easily with the consequences. The weakness in this argument is that, while Israel does not now face strategic issues it can’t handle, it could in the future. Indeed,while Netanyahu is urging action on Iran, he knows that action is impossible without U.S. involvement....

We find it difficult to imagine how a two-state solution would work, but that concept is at the heart of U.S. policy and Obama wants the victory. He has put into motion processes to create that solution, first of all, by backing Netanyahu into a corner. ..."
