“I have no doubt that if diplomatic talks fail with Iran and Tehran doesn’t stop accelerating its nuclear development – U.S. President Barack Obama will conduct a military attack against Iran,” Israel’s President Shimon Peres told Israel Hayom in an interview.

“Preventing Iran from acquiring a nuclear weapon isn’t only an Israeli interest, but a global and an American interest. As long as the U.S. is in the lead — why shouldn’t we use its assistance?” Peres said during the interview with the Israeli paper ahead of the country’s 65th anniversary celebrations next week.

“It could be that the Iranians are trying to buy time, but they are also losing. The situation in Iran is greatly deteriorating, the economy is collapsing, and the people understand this very well,” said Peres.

On Monday, U.S. Secretary of State John Kerry told Peres in a meeting that “President Barack Obama is not bluffing when he says he will stop Iran’s nuclear program.”

“We understand the nature of the threat of Iran. And as the President has said many times — he doesn’t bluff. He is serious. We will stand with Israel against this threat and with the rest of the world, who have underscored that all we are looking for is Iran to live up to its international obligations. No option is off the table. No option will be taken off the table,” Kerry said.

Talks between Iran and the six world powers earlier this week in Kazakhstan proved fruitless, with both sides saying there was “some distance” between them on the issue of Iran’s nuclear program.

On Tuesday Iran announced the opening of two new uranium mines and a new plant that would help to speed up uranium enrichment, a key component in the development of a nuclear weapon.
