The decision of the Iranian authorities to close the Strait of Hormuz would be a "terrible mistake" and would entail a response from the United States. This was announced on June 22 by US Secretary of State Marco Rubio.
"This will be another terrible mistake, economic suicide for them… This will hit the economies of other countries much harder than ours. This would be a large—scale escalation that would require a response not only from us, but also from other countries," he said in an interview with Fox News.
