They kind of are. Iran has been attacking everyone in the Middle East for decades, occasionally seizing or destroying ships in Hormuz, and funding internal dissent. Things are worse right now, but not that much worse, and the short-term pain might very well be worth it for the long-term reduction in Iran's capabilities.
Uh, from the UAE's perspective it is much worse. They sold many $Bs worth of oil and had become a global tourist hub, now they can't do those things. They are being patient for the time being but there's a limit. We don't know what that limit is but if 6 months go by and the Strait's not open can we really expect them to not pay Iran a toll and price their oil in yuan?
What are you talking about? This level of escalation hasn’t happened for at least a quarter century. I know, because I’ve lived in the gulf for large parts of that period
