Other things have changed notably for the better in American-Israeli relations since Mr. Netanyahu called off his last visit to the White House to rush home to deal with the crisis after Israel’s deadly attack on a humanitarian aid flotilla sailing to Gaza in late May. His agreement to ease the land blockade on Gaza, which came at the request of the United States, has helped thaw the chill between the governments, American and Israeli officials said.

Meanwhile, the raft of new sanctions against Iran over its nuclear program, after the passage of the United Nations resolution, has reassured Israelis, who viewed Mr. Obama’s attempts to engage Iran with unease. Mr. Obama signed the American sanctions into law on Thursday.

“The overall tone is more of a feel-good visit than we’ve seen in the past,” said David Makovsky, director of the Project on the Middle East Peace Process at the Washington Institute for Near East Policy. “It has been more focused on making sure that the Ides of March have passed.”

He was referring to the dispute during a visit to Israel by Vice President Joseph R. Biden Jr. in March, when Israel approved plans for Jewish housing in East Jerusalem. Mr. Obama was enraged by what he perceived as a slight to Mr. Biden, and when Mr. Netanyahu visited a few weeks later, the White House showed its displeasure by banning cameras from recording the visit.

But despite the better atmospherics, some analysts said the nuclear nonproliferation issue symbolizes why Israel remains insecure about the intentions of the Obama administration. In addition to singling out Israel, the document, which has captured relatively little public attention, calls for a regional conference in 2012 to lay the groundwork for a nuclear-free zone in the Middle East. Israel, whose nuclear arsenal is one of the world’s worst-kept secrets, would be on the hot seat at such a meeting.
