Iran's move to threaten new enrichment comes at a sensitive moment in the region. Over the weekend,the US rushed an aircraft carrier group and other military assets to the Middle East to confront an unspecified Iranian threat.
Despite Iran's announced deadline to pull out of the remainder of the nuclear deal,there have been signs that Tehran is willing to talk. Foreign Minister Javad Zarif said during a visit to New York last month that he thinks Trump wants to deal but is trying an antagonistic approach at the direction of senior aides and Middle Eastern allies.

"Try the language of respect,"he urged him,pretending to address the president directly."It won't kill you,believe me."
Trump himself says he's ready to talk."We call on the regime to abandon its nuclear ambitions,change its destructive behaviour,respect the rights of its people and return in good faith to the negotiating table,"he said in announcing the new sanctions.
Mark Dubowitz,chief executive of the Foundation for Defence of Democracies,and a critic of the deal,said:"Zarif today is doing what Zarif does very well,which is setting the table for negotiations because I think the Iranians are now realising that they may not be able to wait Trump out."

"The economy is in such bad shape and getting worse that they may experience a massive economic crisis before January 2021,"when either Trump starts a second term or a new American president takes office."I think Zarif can't wait to get back to the table,"Dubowitz said.
But Democrats used Iran's announcement as an opportunity to criticise Trump for withdrawing from the deal. Senator Chris Murphy called it a sign of"blind,meandering,escalatory"foreign policy.
"Iran's moves to restart their nuclear program are a direct consequence of the Trump administration withdrawing from the Iran deal,"said Murphy,a member of the Senate Foreign Relations Committee.
Brian Hook,US envoy to Iran,told reporters at the State Department that the US laid out 12 demands last year for a new Iran deal and an end to the Trump administration's maximum pressure campaign.

They include an end to all uranium enrichment,ceasing all support for militant groups in the Middle East and the release of all US citizens detained in Iran on what the administration considers illegitimate grounds.
The United States,Germany,Britain,France,Russia,China and the European Union signed the 2015 deal with Iran,which lifted international sanctions in exchange for Tehran limiting its nuclear program,including restricting uranium enrichment for 10 years.
Travelling in London,Secretary of State Mike Pompeo issued a restrained response to Iran's announcement. He said America"will wait and observe"what Iran does next."They have made a number of statements about actions they have threatened to do in order to get the world to jump,"Pompeo said.
Tim Morrison,senior director for weapons of mass destruction under national security adviser John Bolton at the White House,was more critical of Iran's threat to violate the nuclear deal.
"Let's be clear,"he said."This is nothing less than nuclear blackmail."
