MOSCOW, Russia -- While world powers met with Iranian negotiators in Geneva, Switzerland, a meeting between Israeli Prime Minister Benjamin Netanyahu and Russian President Vladimir Putin in Moscow essentially fell flat.
Netanyahu is engaged in high-stakes diplomacy to prevent Russia and other Western countries from signing a deal with Iran over its nuclear program.
Netanyahu and Putin took different views from those talks. Putin was optimistic.
"We hope in the near future a deal will be announced acceptable to all the sides," the Russian president said.
But Netanyahu warned once again about the danger of a nuclear Iran.
"For Israel, the biggest threat against us and against global security is Iran's effort to arm itself with nuclear weapons," he said.
Some see Netanyahu's attempt to change Putin's mind as a long shot.
"I think the prime minister tried to convince Putin that agreement with Iran at the moment will be a bad idea," Israel Public Radio's Moscow correspondent Yair Natov told CBN News. "But I think he knew that it would be a very hard task. And from what we saw in the press conference, I think both sides agreed not to agree."
Netanyahu's Moscow visit is one part of an all-out diplomatic campaign by Israel to stop the international community from striking a deal with Iran that would allow it to get a nuclear device.
Israel doesn't want Geneva 2013 to become Munich 1938. That's when the Western powers appeased Adolph Hitler, and he took over Czechoslovakia. That agreement sowed the seeds of World War II.
Mark Regev, spokesman for the prime minister, called it a "dream deal" for Iran.
"The deal on the table is a deal that gives the Iranians exactly what they want," Regev told CBN News. "It's a dream deal. They don't have to make any significant concessions and at the same time they get easing of sanctions. For them it's a dream deal -- a dream deal -- and we're concerned for the international community, it will be a nightmare."
Regev said Iran is not just an Israeli problem.
"It's obvious the Iranian threat is a problem for Israel, that's clear," Regev said. "I'll remind you that the Iranians are working on intercontinental ballistic missiles -- missiles that can carry nuclear payloads."
"Now they don't need those missiles for Israel because they've already got missiles that can target Israel," he said. "Those missiles are being built for targets way beyond the Middle East -- Europe and North America."
But will Israel attack Iran's nuclear facilities?
In a statement designed to remind negotiators in Geneva a military option is very much alive, Israel's former national security advisor Ya'akov Amidror told the Financial Times, "…We have enough to stop the Iranians for a very long time."
"We are not bluffing," he continued. "We are very serious about preparing ourselves for the possibility that Israel will have to defend itself by itself."
