Before 15 November 2019, will there be a lethal confrontation between the national military forces of Iran and the United States either in Iran or at sea?
Recent attacks on Saudi Arabian oil and gas infrastructure have further aggravated regional tensions in the Middle East (Al Jazeera, CNN). While Houthi rebels in Yemen have claimed responsibility, accusations have been levied against (and denied by) Iran (BBC, CNBC). A lethal confrontation is one that results in at least one fatality (total, not each) for the national military forces of either side. For the purposes of this question, Iran's national military forces include the Revolutionary Guard Corps and Law Enforcement Forces.
The question closed "No" with a closing date of 15 November 2019.
