I think they were speaking in terms of operational proficiency, not strategic wisdom. Whether or not you think assassinating Qasem Soleimani was a good idea, we inarguably did a very good job of it.
Illegally assassinating a foreign official on another country’s territory, in a place where any military activity is prohibited, is not only ill-advised, it’s extremely unimpressive. And we all know very well whose help was involved.
