Maybe. But the Iran conflict also ties in with the Ukraine war, which is an assertion of Russian power into that US-Europe/China duopoly. And it's happening at the same time as the former alliance is breaking.

It's possible that it will be a regional conflict the way the Serbian/Austro-Hungarian conflict was regional. Or the way people pretended that the Germany/Sudetenland conflict was regional.

I don't wish to catastophize. But I also think it's important to realize that this does have the potential to become much worse very suddenly. That doesn't make the decisions easy, but they shouldn't be easy.
