Why is Trump threatening to bomb Oman, the Iran mediator trying to clear Hormuz?

The world knows that US President Donald Trump is angry with Iran. But he is not happy with the small country lying across the Strait of Hormuz from the Islamic Republic, either: Oman.Oman has played a relatively low profile role since the Iran war began, including as a mediator. But its geography has thrust the sultanate into the uncomfortable position of negotiating with Tehran over management of the strait while facing Trump’s threats.Trump this week told Fox News reporter Trey Yingst that the US would bomb Oman if it “gets in the way”, using an expletive for emphasis. It is not the first such threat he has made. Oman’s foreign ministry did not immediately respond to emailed questions about Trump’s threat and when Oman and Iran might issue a joint statement on their deal.
