The escalation comes amid broader regional tensions and raises urgent questions about how Washington will respond to protect freedom of navigation in a waterway its own naval forces regularly use. Military analysts warn that the combination of physical attacks and route mandates represents a more aggressive Iranian posture than previous episodes of harassment in the Gulf region.
