Under the terms of a recent memorandum of understanding, Iran is expected to restrain its proxy group Hezbollah, while the U.S. is expected to constrain Israel.

The entire negotiation process is intended to be completed within a 60-day timeline.

Senior Trump administration officials predict they can determine if Iran is negotiating in good faith within just a couple of weeks.

Secretary of State Rubio is running separate negotiations between representatives of Israel and Lebanon at the State Department in Washington.

For comparison, the Obama-era nuclear deal (JCPOA) took 20 months of intense negotiations to finalize.

Hawkish members of the Trump administration would have preferred to continue applying pressure on Iran rather than entering into the current diplomatic agreement.

The memorandum of understanding between the U.S. and Iran stipulates that Iran would restrain its proxy group Hezbollah, while the U.S. would constrain Israel to achieve a ceasefire in Lebanon.
