Optimism for revised accord following 16 months of negotiations.

Diplomats say they imagine they’re near restoring the Iran nuclear deal, 4 years after the US pulled out.

For the previous 16 months, negotiators from Washington and Tehran have been working with the opposite signatories to reestablish the accord.

The European Union laid down what it referred to as its closing supply earlier this month.

Few particulars have been formally made public, however sources have instructed Al Jazeera the brand new deal shall be rolled out in 4 phases throughout two 60-day durations.

The EU’s international coverage chief says Tehran has given what he calls a “cheap” response to the proposal.

All sides are ready for the US to answer.

So what are the ultimate hurdles to a brand new settlement?
