"Daylight" between the United States and Israel.

From a Wall Street Journal article by Mitt Romney:

The president began his term with the explicit policy of creating "daylight" between [he United States and Israel]. He recently downgraded Israel from being our "closest ally" in the Middle East to being only "one of our closest allies." It's a diplomatic message that will be received clearly by Israel and its adversaries alike. He dismissed Israel's concerns about Iran as mere "noise" that he prefers to "block out." And at a time when Israel needs America to stand with it, he declined to meet with Prime Minister Benjamin Netanyahu.

In this period of uncertainty, we need to apply a coherent strategy of supporting our partners in the Middle East—that is, both governments and individuals who share our values....

It means placing no daylight between the United States and Israel.
