Republican Senator Scott Walker on Tuesday said if elected he wanted to take the fight directly to Iran.
“I will terminate that deal,” said Walker. “I will put in place crippling economic sanctions on Iran, and I will convince our allies to do the same.”
"The deal allows Tehran to dismantle US and international sanctions without dismantling its illicit nuclear infrastructure,” the Wisconsin governor said.
Iran and the P5+1 group of countries -- the US, Britain, France, China, Russia plus Germany -- reached a conclusion on the Joint Comprehensive Plan of Action (JCPOA) in Vienna on Tuesday.
According to the text of the Joint Comprehensive Plan of Action, Iran will be recognized by the United Nations as a nuclear power and will continue its uranium enrichment program.
The JCPOA will put limits on Iran’s nuclear program in exchange for the removal of sanctions against the Islamic Republic.
Jeb Bush, another Republican candidate, criticized President Barack Obama over approving the Joint Comprehensive Plan of Action (JCPOA), saying it was not diplomacy, but appeasement.
"The nuclear agreement announced by the Obama Administration today is a dangerous, deeply flawed, and short sighted deal," he said on Tuesday.
"Based on initial reports and analysis, it appears this agreement does not 'cut off all of Iran’s pathways to a nuclear weapon' -- in fact, over time it paves Iran’s path to a bomb," former Florida governor claimed.
Echoing the criticism of his fellow Republicans, Ted Cruz attacked the US president for concluding the nuclear talks.
Senator Marco Rubio of Florida also blasted the agreement on Iran’s nuclear program, saying Obama has “consistently negotiated from a position of weakness.”
“I have said from the beginning of this process that I would not support a deal with Iran,” said Rubio.
The 2016 GOP presidential candidate went on to say, “I believe that this deal undermines our national security.”
Under the compromise agreement passed by Congress and signed by President Obama, the Republican-controlled Congress has a 60-day period to review the conclusion and subsequently vote to either approve or disapprove its implementation.
House speaker John Boehner also repeated the Republicans’ rhetoric towards Tehran, saying, the move “will hand Iran billions in sanctions relief while giving it time and space to reach a break-out threshold to produce a nuclear bomb - all without cheating.”
Obama, however, vowed to veto any legislation from lawmakers that "prevents the successful implementation of the deal."
If every single Republican in the House votes against the agreement, 44 Democrats would need to join them to form a veto-proof majority. Given the same scenario in the Senate, 13 Democrats would have to join the Republicans.
