I don't get it. Why did the price of oil basically not move despite everything?

Brent closed at around $108 on Thursday.

Since then, we've had increased aggression in addition to all kinds of threats from the U.S, with Iran ignoring them completely.

Overnight trading opened, Brent won a couple of % then lost them right away, and is trading at around $108.

I don't understand at all. Can someone explain?
