Yeah, the boats appearance was what was weighting me towards agreeing with you. I still don’t think you just “shoot and destroy any and all Iranian gunboats if they harass our ships at sea.” And it was even subsequently stated that there was no actual change in the USN rules of engagement despite Trumps tweet. It still has to rise above the level of harassment.
I realize the time between harassment and attack is small here, and I am in no way envious of the UNS sailor on the trigger there.
