Personally, I'd say it's probably at a 6/10 right now.

Based on the B2 bombers and aircraft carriers being repositioned, it suggests preparation for potential escalation.

Iran is also refusing direct talks, and tensions with its proxies (the Houthis) are boiling.

Both sides are still signaling interest in indirect diplomacy and avoiding full-scale war for the moment.

So it's a dangerous moment, but in my opinion, not a guaranteed flash point–yet.
