Looks like a military strike.

Actually it’s economic leverage.

The U.S. hit military targets on Kharg Island, Iran’s primary oil export hub.
But the oil infrastructure itself was deliberately spared.

Kharg handles the majority of Iran’s crude exports.

Destroying those terminals would collapse Iran’s oil revenue overnight and likely trigger a global oil shock.

Instead the signal is conditional:

Keep the Strait of Hormuz shipping lanes open, and the oil facilities remain untouched.

Interfere with shipping, and Iran’s export lifeline disappears.

Military pressure backed by economic leverage.

The oil stays online only as long as the shipping does.
