The US called the condition of returning to the nuclear deal with Iran

The United States said on Tuesday (Feb 2) it was too early to accept an Iranian proposal for the EU to help revive a nuclear deal, reiterating calls on Tehran to come into full compliance.
President Joe Biden supports a US return to the 2015 deal, known as the Joint Comprehensive Plan of Action, but has not changed his position that Iran must take action first.
"If Iran comes back into full compliance with its obligations under the JCPOA, the United States would do the same," the State Department's new spokesman, Ned Price, told reporters.
The administration will be "consulting with our allies, consulting with our partners, consulting with Congress before we're reaching the point where we're going to engage directly with the Iranians and (be) willing to entertain any sort of proposal," Price said.
