In announcing the United States pullout Tuesday, Trump dismissed the accord as an "embarrassment" that was "defective at its core" and called for a "new and lasting deal".
"We always knew Iran was making a nuclear bomb, and they continued and got what the wanted, so it's good that Trump and Netanyahu did this together".
The deal was signed in 2015, under President Barack Obama, and curbed Iran's nuclear activities in exchange for widespread sanctions relief.
"... The consistent flouting of agreements that our country is a party to risks eroding America's credibility, and puts us at odds with the world's major powers".
"We will not allow American cities to be threatened with destruction and we will not allow a regime that chants "Death to America" to gain access to the most deadly weapons on Earth". It was not clear what guarantees Iran was seeking from the other signatories.
Late Tuesday night, President Hassan Rouhani said he'd be sending Iranian Foreign Minister Mohammad Javad Zarif to the countries still in the deal - China, France, Germany, Russia and the United Kingdom.
"It might make Iran change its path", he said hopefully. Iran will "likely increase" certain aspects of the program, but will "stay away" from drastic measures that could prompt an Israeli or US military strike, the note said.
The decision marked a stark diplomatic defeat for Europe, whose leaders, repeatedly and in person, begged the mercurial U.S. leader to think again.More news: Nintendo Reportedly Recruiting Level Designers For New Zelda Game

And, "Trump's decision does the actual opposite of showing the US isn't serious about its commitments - it communicates to the world that there's a new sheriff in town who is going to follow through on what he says, unlike Obama (of the infamous red line in Syria)".
"We're out of the deal". "We agreed on the nuclear pact", he said.
It also stressed that United States sanctions on Iran would lead to a drop in Iranian oil exports and put more pressure on the world oil markets, banks, transport companies, insurance companies and ports, which will be exposed to losing access to the global banking system, and will have no choice but to end their partnership in Iran.
In a sign of the depth of European displeasure, plans are being drawn up in Brussels to introduce measures blocking U.S. sanctions, an extremely rare move against an allied government.

However, the deal came with time limits and did not address Iran's ballistic missile program or its support for militant groups across the region branded as terrorists by the West. Trump has repeatedly pointed to those omissions in referring to the accord as the "worst deal ever".
Trump's decision offers him a domestic political victory, fulfilling a longstanding campaign promise and underscoring his no-nonsense political brand.
Will it - as feared - stoke more conflict in the Middle East.
Kaplan said Trump's move "can only be attributed to one or more of three motives: a misunderstanding of the deal's terms, a need to torpedo yet another one of President Obama's accomplishments, or a desire to weaken or destroy the government of Iran". The exhortation from Khamenei, who has final say on all state matters, follows a pattern of Iranian leaders declaring their nation's ability to resist foreign pressure or interference.
