Condemning the United States President Donald Trump's decision of reversing landmark 2015 Iran's nuclear deal, world leaders have said that this action will amount to the growing isolation of the U.S. and destabilize the Middle East.
European Union foreign policy chief Federica Mogherini said the accord "is a robust deal that provides guarantees and a strong monitoring mechanism so that Iran's nuclear program is, and will remain, exclusively for civilian purposes only."
She added that the "agreement is working and cannot be terminated by Trump".
British Prime Minister Theresa May, German Chancellor Angela Merkel and French President Emmanuel Macron said they "stand committed" to the Iran nuclear deal and are" concerned by the possible implications" of Trump's decision to re-certify the deal to Congress.
"The nuclear deal was the culmination of 13 years of diplomacy and was a major step towards ensuring that Iran's nuclear program is not diverted for military purposes," they added.
Iranian, Russian and European leaders said that President Trump's decision will destabilise the Middle East and could make it harder to resolve the growing tensions on the Korean Peninsula.
President Trump has threatened to terminate the 2015 Iran nuclear deal if Congress and US allies fail to amend the agreement by fixing serious flaws in significant ways.
However, Israel, Saudi Arabia and the United Arab Emirates have welcomed President Trump's stance.
The New York Times quoted Israeli Prime Minister Benjamin Netanyahu as saying that Trump's announcement created "an opportunity to fix this bad deal" and was a sign of his determination to "boldly confront Iran's terrorist regime."
President Trump on Friday threatened to pull out of a deal reversing Iran's nuclear program if Congress and US allies do not agree to strengthen it, as he unveiled a tough and comprehensive new policy toward the Islamic Republic.
"As I have said many times, the Iran deal was one of the worst and most one-sided transactions the United States has ever entered into," Trump said in a major speech at the White House.
Trump accused Iran of committing "multiple violations of the agreement," despite the fact that the International Atomic Energy Agency, America's European allies and even his own government say that "Tehran is complying with the 2015 deal agreed by former President Barack Obama and major world powers".
