"If diplomacy is to work, those pressures must be kept in place," Netanyahu said during an Oval Office meeting with Obama.
The two leaders met at the White House just days after Obama's historic phone call with new Iranian President Hassan Rouhani. The 15-minute call marked the first direct conversation between U.S. and Iranian leaders in more than 30 years.
Obama credited the flurry of U.S. sanctions that have crippled Iran's economy with bringing Rouhani to the negotiating table. While he said it was important to "test diplomacy," the president also said that Rouhani must back up his more conciliatory words with actions that give the international community confidence that Iran is not seeking to produce a nuclear weapon.
"We enter into these negotiations very clear-eyed," Obama said, adding that while he preferred a diplomatic solution, all options remain on the table, including military action.
Obama and Netanyahu, whose tense relationship has somewhat improved in recent months, also addressed the tenuous peace talks between Israel and the Palestinians, the bloody civil war in Syria, and unrest in Egypt, the first Arab country to forge a peace treaty with Israel. The two leaders had not met in person since March, when Obama made his first trip to Israel as president.
The sudden prospect of diplomacy with Iran overshadowed a host of pressing issues on the U.S.-Israeli agenda. Netanyahu has long been skeptical of Obama's preference for negotiating with Iran, repeatedly pressing his U.S. counterpart to issue credible threats of military action if Tehran gets close to producing a nuclear weapon.
Sitting side-by-side with Obama, Netanyahu echoed his recent warnings that the U.S. and other Western nations should not be swayed by Rouhani's courtship. Israelis derisively called Iran's efforts the "smiley campaign."
"The ultimate test of a future agreement with Iran is whether or not Iran dismantles its military nuclear program," he said.
Iran has offered to open its nuclear facilities to international inspectors as part of broad negotiations with the United States but has insisted that its nuclear program is its right and is for peaceful purposes only. The U.S., Israel and other allies have long accused Iran of seeking a bomb. Iran says it is enriching uranium for peaceful purposes.
