President Donald Trump's decision to withdraw from the Obama Era deal will have a sizable effect on international affairs. Rochester area experts say that this is another act of diplomacy that isolates America from its historical allies.

"It's really complicated because it's not only withdrawing the United States from this particular arrangement, but it calls into question Washington's commitment to one, the international regime that governs nonproliferation and also all of the other types of agreements we have with our allies," said St. John Fisher Political Science Department Chair Wes Renfro.

"What they saw in that treaty and that agreement that we signed did not seem to be the same things that the president was focused on today," said Margaret Corbin with the United Nations Association of Rochester.

With the Russia investigation in full swing, experts are questioning whether the move was truly to fulfill a campaign promise, or if the motives were diversionary.

"It's a lot of posturing, a lot of scare tactics, worry, concerns. We need to constantly work on ways to work together," said Corbin.

"My sense is that the withdrawal from this deal is much more about Donald Trump scoring points with his base in the U.S. than pursuing smart diplomacy," said Renfro.

Senator Kirsten Gillibrand released a statement addressing the concerns that withdrawing from the deal removes the ability to maintain a strong coalition holding Iran accountable.

"By walking away from the agreement, the President has opened the door to Iran going back to developing a nuclear weapons program. This unilateral decision will cost us the ability to maintain a strong coalition holding Iran accountable," said Gillibrand.

"I'm reluctant to say that there is no concern over the prospect of nuke exchange. I think that there is more concern in 2018 than there was in 2015, or 2005 or 1995 for that fact but I also don't feel comfortable saying that we should devote a lot of time seriously worrying about this," said Renfro.

President Obama who signed the Joint Comprehensive Plan of Action in 2015, released a statement on Twitter and Facebook, saying that the agreement was in America's best interest while calling out Trump's poor diplomacy.

"The JCPOA is in America’s interest – it has significantly rolled back Iran’s nuclear program. And the JCPOA is a model for what diplomacy can accomplish," said Obama.

"Talking is less expensive and less dangerous than war," added Corbin.
