Trump ends Iran nuclear deal calling it 'disastrous'

President Donald Trump said Tuesday that he's ditching the Iran nuclear deal, calling it 'disastrous' and an 'embarrassment.' 

Trump said that the U.S. now has 'definitive proof' that Iran was lying about its pursuit of nuclear weapons when it entered into the 2015 agreement. And he threatened Tehran's mullahs with new headaches if they resume their pursuit of a weapon of mass destruction.

'If the regime continues its nuclear aspirations, it will have bigger problems than it has ever had before,' the president warned. 'It is clear to me that we cannot prevent an Iranian nuclear bomb under the decaying and rotten structure of the current agreement.'

'The Iran deal is defective at its core. If we do nothing, we know exactly what will happen: In just a short period of time, the world's leading state sponsor of terror will be on the cusp of acquiring the world's most dangerous weapons.' 

Barack Obama and his former secretary of state John Kerry both bashed Trump's decision, calling it unnecessary and wrongheaded.

Iranian president Hassan Rouhani responded, telling his country's state-run TV network: 'I have ordered Iran's atomic organization that whenever it is needed, we will start enriching uranium more than before. Rouhani said Iran would start ramping up production 'in the next weeks.'

Rouhani blasted Trump immediately after Tuesday's speech.

'Iran will be conferring with the world's two super powers, Russia and China,' he sniped, insisting that Trump's 'psychological war and economic pressures will not work.'

Leaders of America's three staunchest European allies – France's Emmanuel Macron, Germany's Angela Merkel and the United Kingdom's Theresa May – issued a joint statement asking the U.S. not to do anything that would prevent them from keeping the nuclear deal intact even without Washington's participation.

Iran 'continues to abide by the restrictions' of the deal, the three leaders said, citing a statement from the International Atomic Energy Agency, adding that 'the world is a safer place as a result.'

'Our governments remain committed to ensuring the agreement is upheld, and will work with all the remaining parties to the deal to ensure this remains the case including through ensuring the continuing economic benefits to the Iranian people that are linked to the agreement,' they said.

The president has been outspoken for nearly three years about the nuclear bargain that he called 'insane' and 'the worst deal in history.'

U.S. Treasury Secretary Steve Mnuchin, whose Cabinet department oversees economic sanctions against rogue regimes, said before Trump's speech that '[w]e will continue to work with our allies to build an agreement that is truly in the best interest of our long-term national security.'

The United States, he said, will cut off Iran's 'access to capital' to fund terrorism, 'its use of ballistic missiles against our allies, its support for the brutal Assad regime in Syria, its human rights violations against its own people, and its abuses of the international financial system.'
