Alternate title: Trump is blowing smoke up your ass and the media is lending a hand.
Possibly a more accurate title too, because all of this saber rattling Trump is doing right now is all smokescreen. Just like the airstrike on that base in Syria or dropping the MOAB on a cave in Afghanistan, the president's threats of "fire and fury" against North Korea is little more than an attempt at distracting the public from all of the negative attention his administration has been getting lately, ranging from Bob Mueller impaneling a grand jury to the six wild days of The Mooch to the FBI raiding Paul Manafort's house the other day as part of an investigation. Every time the attention gets to be too much, Trump tries to draw attention away via military action or as with North Korea, the threat of action.
But what of all these articles the news media is publishing about the escalation between America and North Korea? It's called collusion. These outlets are all keenly aware that those articles will get instant clicks like any other clickbait and that means a very welcome uptick in revenue. The media is more than happy to slap a sensationalist headline on to an assembly-line article and watch all those hits and ad money come pouring in. Saber rattling is good for the bottom line and the news media is more than happy reap the benefits.
But the reason why we're not going to fight North Korea is for the very simple fact that China will not allow it to happen. NK may talk big about hitting Guam or punishing America for the new sanctions, but at the end of the day, there's no way in high holy hell that Beijing is going to let them start a fight against the U.S.. They are keenly aware that such a conflict would inevitably draw them into it and one thing we can all agree on is that two nuclear equipped countries ought never to fight because of the potential for a Big Boom.
My two cents is that China undoubtedly has people in the North Korean government in their pocket and the instant they catch wind of Kim Jong-un tries to order any kind of attack, Beijing is going to nip it in the bud, either by warning him off, doing the world a favor and putting a bullet in his head, or by removing his ability to launch missiles of any kind via airstrikes. There's even a slim possibility that China decides that having a unified Korea is preferable to living in the Fallout games.
