What are Iran's options to escalate further in face of US economic threats? – explainer

Following US threats of severe sanctions, Iran is considering various escalation options to counter economic pressure. Mohsen Rezaei, Secretary of Iran's Supreme National Security Council, stated, "If the economic war continues, not a single drop of oil will be exported, neither through the Strait of Hormuz nor from anywhere in the Persian Gulf." Iran has already significantly disrupted shipping in the Strait of Hormuz and blacklisted 45 tankers. Additionally, its Houthi allies are restricting Red Sea shipping, causing Chinese companies to reroute. Iran has also threatened "earthquake" force retaliation against neighboring countries participating in US economic efforts, targeting US bases and energy infrastructure. While direct attacks on Western countries are challenging, Iran has been accused of cyberattacks and recruiting individuals for attacks abroad.
