"Make no mistake: those who adhere to the ideology of rejecting Israel's right to exist might as well reject the earth beneath them and the sky above, because Israel is not going anywhere. Today, I want to tell you — particularly the young people — that so long as there is a United States of America, Atem lo levad, you are not alone." — Obama
Both presidents essentially commit the might of the United States to protect Israel.
_Relations with Arab World:
"This fundamental insight, that freedom yields peace, is the great lesson of the 20th century. Now our task is to apply it in the 21st. Nowhere is this work more urgent than here in the Middle East. We must stand with the reformers working to break the old patterns of tyranny and despair. We must give voice to the millions of ordinary people who dream of a better life in freedom. We must confront the moral relativism that views all forms of government as equally acceptable and thereby consigns whole societies to slavery. Above all, we must have faith in our values and ourselves and confidently pursue the expansion of liberty as the path to a peaceful future." — Bush
"This truth is more pronounced given the changes sweeping the Arab World. I recognize that with the uncertainty in the region — people in the streets, changes in leadership, the rise of non-secular parties in politics — it is tempting to turn inward. But this is precisely the time to respond to the wave of revolution with a resolve for peace. As more governments respond to popular will, the days when Israel could seek peace with a handful of autocratic leaders are over. Peace must be made among peoples, not just governments. No one step can change overnight what lies in the hearts and minds of millions." — Obama
