Over the past week, the conflict between the United States and Iran has gone from a simmering tit-for-tat to something that much more resembles all-out war.

US President Donald Trump last week threatened to broaden the war unless Iran stops attacking ships transiting the Strait of Hormuz.

In recent days, the US has expanded its targets beyond Iranian coastal sites housing radar and drone facilities to include roads, tunnels, railways, port infrastructure and, according to Iranian media, a desalination plant.

Iran has, in turn, expanded its target list across seven countries in the region, and official media outlets have suggested that major ports in Gulf Arab states may soon be added. Kuwait has borne the brunt of Iranian strikes, with a desalination plant and oil refinery damaged. Jordan too has seen regular barrages.

The conflict is at an inflection point. It might give way to yet another round of mediation and negotiation. But to most analysts, that seems unlikely. Neither side seems in the mood to talk; both have said that the memorandum of understanding (MoU) agreed in June after weeks of tortuous negotiation is no longer in effect.
