The only countries going to war with Iran are Israel and USA. The other countries are negotiating with Iran and reportedly paying the toll. Also, the strait has been open to Spanish tankers since two weeks ago.
But no Spanish tankers have gone through so that doesn't seem to be accurate. An Iranian diplomat saying that publicly doesn't matter when the irgc continues to shoot them. The only known European aligned tanker to have gone through is this French one we are reading about here.
In this particular case, it is a diplomatic and reciprocal gesture of goodwill from Iran - the French have publicly said that joint military operations to open the Strait is a bad a idea and diplomatic options need to be pursued for the same while the Japanese have confirmed that they won't be sending any minesweepers to the Strait (Japan Isn’t Sending Minesweepers to Middle East, Takaichi Says - https://www.bloomberg.com/news/articles/2026-03-12/japan-isn... ). Oman, of course, has been the mediator in the early US-Iran negotiations, and has publicly said Iran cannot be blamed for the US-Israel attacks ('This war is not of their making,' Omani foreign minister says of Iran - https://www.middleeasteye.net/news/war-not-their-making-oman... ) as it had accepted a new nuclear deal with the Trump administration during the negotiations (Peace ‘within reach’ as Iran agrees no nuclear material stockpile: Oman FM - https://www.aljazeera.com/news/2026/2/28/peace-within-reach-... ). He has blamed the Trump administration for undermining negotiations and implied that they acted in bad faith.
