National Security Adviser John Bolton told CNN’s Jake Tapper Sunday that “the consequence of the United States getting out of [the Iran deal]” is a re-imposition of the sanction regime that was in place before the Obama administration entered the U.S. into the now-failed deal.

“I think what we’ve seen is that Iran’s economic condition is really quite shaky so the effect here could be dramatic,” Bolton said. “We have the support of Israel, we have the support of the Arab oil-producing monarchies and many others and the consequences of American sanctions go well beyond goods shipped by American countries because of our technology licenses to many other countries and businesses around the world.”

Tapper, who asserted that the U.S. was “going it alone” in pulling out of the Iran deal, and referring to statements made by President Donald Trump, asked Bolton if sanctions might be forthcoming for European companies who work with Iran because it might be perceived as an attempt to help Iran in their nuclear ambitions.

“I think the Europeans will see that it’s in their interests ultimately to come along with us,” said Bolton. “Despite the complete consistency of President Trump in his opposition to the deal…I think at the moment there’s some feeling in Europe that they’re really surprised we got out of it…the answer [to if European companies could be sanctioned] is: it’s possible. It depends on the conduct of other governments.”
