Fearing the repercussions of a total regime collapse in Iran, Gulf Arab states have intensified their outreach to the Trump administration and Tehran over the past week.

President Donald Trump will decide in the next two weeks whether the U.S. will get involved in the Israel-Iran air war, the White House said on Thursday, raising pressure on Tehran to come to the negotiating table.

If the United States bombs an underground uranium enrichment facility in Iran or kills the country’s supreme leader, it could kick off a more dangerous and unpredictable phase in the war.
