After Trump on Tuesday announced he would pull out of the Iran nukes deal, Iran's supreme leader on Wednesday blasted the US president over the move, and the Islamic Republic's lawmakers lit a paper USA flag on fire inside their parliament building, amid shouts of "Death to America!" from lawmakers, global media reported.
"It's not yet clear to us or to Europe what that means in respect of existing export levels in the eyes of the United States", Mr Parker said.
President Donald Trump warned Iran of "very severe" consequences should the country restart nuclear activities that were halted as part of the 2015 accord he abandoned on Tuesday.
Former CIA director John Brennan said Trump's "madness" had "undermined global confidence in United States commitments, alienated our closest allies, strengthened Iranian hawks, & gave North Korea more reason to keep its nukes".
But the long term impact for USA foreign policy and for the Middle East was less clear.
"Now President Trump has ceded the moral high ground and freed Iran from all those constraints".
As part of the US withdrawal from the deal, heavy economic sanctions will be re-imposed on the regime again.
While Netanhayu's pitch to Trump may have worked, his argument was undermined by his own military chiefs, who have said the deal is working and has delayed Iran's nuclear capability by 10 to 15 years.
"Iran is subject to the world's most robust nuclear verification regime", said International Atomic Energy Agency (IAEA) director-general Yukiya Amano.
"I don't have much confidence in the Europeans growing a spine anytime soon, but the Russians and the Chinese are much more reliable partners for Iran".

In turn, Iranian Revolutionary Guard Corps Commander Major General Mohammad Ali Jaafari positively reviewed the USA withdrawal. He declared he was making the world safer, but he also deepened his isolation on the world stage and revived doubts about American credibility with a rationale that contradicted the analyses of US and foreign intelligence sources.
So what is the Iran deal, exactly? Yet they still left convinced he was likely to re-impose sanctions.
