His response was to mock them for their incompetence and reiterate his promise that they will never get nukes while he is President and they will never escape his wrath if they harm an American, then he pointed out they were “standing down” after their failed missile attack that they were telling their own people was a success.
He rubbed salt in their terrorist wounds and they know good and well that he means every word he says, so do the people of Iran who are watching their leaders incompetence and cowardice.
Except for the those who are claiming that they “missed on purpose” everyone knows that Iran has absolutely no capacity to do anything but suffer if they mess with Trump, which is a pretty good response I think
I also like his consistent message that his actions reveal, that responding with force does not mean we are entering a “War”; all the crybabies who can’t seem to understand that knocking a bully on his butt every time he picks a fight does not require a prolonged fight to rehabilitate their country. You just blow up their stuff and go back to the business of fixing America, if they don’t get the message you blow more stuff up until you find something that they care enough about losing to send them back under the rocks they belong under.
