Latest on Iran as Trump releases new statement (youtube.com)
Trump's main point was that Iran has been run for almost 50 years (we've all seen the photos of a more casual, modern, smiling Iran from the 60s and 70s) by a regime hating America, that they're the 'number one state sponsor of terror', that they want a nuke, and that America is the most powerful country so it can do something. Trump rebuilt the military, he said, and it's more competent now.
Part of the reason we are so against American wars is the previous 60 years of them have been mixed purpose, and then later, perceived as nothing more than endless wars to stimulate the MID.
It doesn't mean America can't change and do a different kind of war. Iran, like Venezuela, isn't intended to be a war. It's not Bush stuff. It's a precision strike and then let Iranians make something else, basically.
