Front-runner Republican US presidential candidate Donald Trump says Iran is going to become an unbelievably rich and powerful nation because of the last month's nuclear agreement in Vienna, Press TV reported.
Trump told NBC News on Sunday that he will not abolish the July 14 conclusion of nuclear talks between Iran and the P5+1 group of countries if he wins the race to the White House.
Trump, however, said that he would supervise the implementation of the agreement very strictly.
Then, he went on to denounce the Obama administration for negotiating "a bad deal" with Iran which he said would "lead to a nuclear holocaust".
"I'm really good at looking at a contract and finding things within a contract," he claimed. "I would police that contract so tough that they don't have a chance."
The controversial Republican candidate then described the US nuclear negotiators including Secretary of State John Kerry as "incompetent".
"The people who negotiated that deal - Kerry and his friends - are incompetent," he said.
Last month, Iran and the P5+1 group of countries - the US, Britain, France, Russia, China, and Germany - announced the conclusion of nuclear negotiations in the Austrian capital Vienna.
According to the text of the Joint Comprehensive Plan of Action (JCPOA), Iran will be recognized by the United Nations as a nuclear power and will continue its uranium enrichment program.
But some restrictions will be placed on Iran's nuclear program in exchange for the removal of sanctions against the Islamic Republic.
Trump said that the accord will put Israel in big trouble. "Iran is going to be unbelievably rich and unbelievably powerful and Israel is in real trouble," he said.
"[Iranians] are going to be such a wealthy, such a powerful nation, they're going to have nuclear weapons. They are going to take over parts of the world that you wouldn't believe. And I think it's going to lead to a nuclear holocaust," Trump alleged.
Rightwing elements in the Republican Party along with Israeli Prime Minister Benjamin Netanyahu and some of their allies accuse Iran of pursuing military objectives in its civilian nuclear program.
Iran rejects the allegation, arguing that as a committed signatory to the nuclear Non-Proliferation Treaty (NPT) and a member of the International Atomic Energy Agency (IAEA), it has the right to use nuclear technology for peaceful purposes.
The Obama administration is striving to save the nuclear agreement in the Republican-dominated Congress which is reviewing it and is likely to vote on it in September.
Analysts say Republican candidates are opposing the nuclear agreement to avoid angering the pro-Israel lobby and preventing their Democratic rivals from getting any political advantage by resolving the Iranian nuclear issue.
