U.S. may escalate military presence or diplomatic negotiations; potential for international coalition responses to ensure freedom of navigation; possible emergency oil reserve releases; increased sanctions or counter-sanctions; UN Security Council involvement likely; insurance and shipping regulations may be modified.
