Iran's logic is simple and easy to understand - if any foreign territory is used to hurt them, they will hurt them in return too. If a water desalination plant in Bahrain was deliberately targeted, the American military there must be responsible for it because Iran has been incredibly restrained in its retaliations:

> Iran said it was the United States that set a precedent for such attacks when it targeted a water desalination plant on Iranian soil. “The US committed a blatant and desperate crime by attacking a freshwater desalination plant on Qeshm Island,” Iran’s Foreign Minister Abbas Araghchi said in a post on X on Saturday. “Water supply in 30 villages has been impacted. Attacking Iran’s infrastructure is a dangerous move with grave consequences. The US set this precedent, not Iran.” ... Meanwhile, Iranian President Masoud Pezeshkian warned on Sunday that Iran would be “forced to respond” against neighbouring countries if their territory is used to attack it. - https://www.aljazeera.com/news/2026/3/8/bahrain-says-water-d...

(Most western news media are terrible when it comes to middle-east reporting and only tend to parrot and enforce a one-sided western narrative.)

As for the fire in UAE’s Fujairah oil industry zone, as the media report say, it was caused by drone derbis (which means damage was caused by a falling debris of a drone that was destroyed mid-air). Nobody has suggested that Fujairah was the target. (Note that Iranian drones and missiles also lack precision. And Fujairah could indeed be a legitimate target for the Iranian military if the American military depends on it too).
