Russia allegedly helping Iran develop carrier-killing supersonic cruise missiles.

This is the kind of geopolitical risk that doesn't show up in your portfolio until it's too late. Defense stocks have been sleepy lately, but headlines like this are reminders that the global security environment is deteriorating fast.

If Iran gets hypersonic anti-ship capabilities, the entire Gulf becomes a no-go zone for U.S. carriers. That changes everything — oil flows, insurance costs, shipping routes, regional power balance.

Watch defense ETFs like $ITA and $XAR. Also keep an eye on oil volatility — any serious escalation in the Strait of Hormuz and crude spikes hard. This isn't priced in yet.
