US Secretary of State John Kerry dismissed Israeli Prime Minister Binyamin Netanyahu's criticism of the nuclear deal reached with Iran as “comments that are way over the top" Tuesday.

"What the critics of this plan never offer... is a realistic alternative," Kerry told MSNBC. "It's wrong for people to think this doesn't have long-term accountability."

"Israel is safer" as a result of Tuesday's accord, Kerry insisted. "This is under attack by people who really don't know the terms of the agreement."

Watch - Kerry criticizes Netanyahu comments:

Kerry said that if Iran fails to meet the requirements of the deal, all options remain on the table.

"The United States doesn't lose anything... by giving them the opportunity to prove this is a peaceful program," Kerry said. "What's the alternative ... go to war now?"

“This deal repeats the mistakes made with North Korea," Netanyahu said earlier. "There, too, we were assured that inspections and verifications would prevent a rogue regime from developing nuclear weapons. And we all know how that ended. The bottom line of this very bad deal is exactly what Iran's President Rouhani said today: the international community is removing the sanctions, and Iran is keeping its nuclear program.”

"The deal will give an unreformed, unrepentant and far richer terrorist regime the capacity to produce many nuclear bombs - in fact, an entire nuclear arsenal, with the means to deliver it.

"What a stunning historic mistake."

Netanyahu also spoke Tuesday evening with US President Barack Obama, following the deal with Iran. He used the opportunity to express Israel's concerns regarding the nuclear deal with Iran.

Warning the agreement threatened the State of Israel's security, Netanyahu stressed two central concerns.

First and foremost, he noted that it will still mean Iran can produce nuclear weapons at a future date - whether in 10-15 years' time when the deal's limitations expire, or by breaking its commitments before that time.

In addition, Netanyahu said, it will funnel hundreds of billions to the terror machine, and the Iranian war that threatens Israel and the entire world.
