From Greg Fallis:
By now, everybody is aware of the colossal fuck-up in which senior Trump national security officials conducted a high level discussion about launching at attack in Yemen using…and it sounds so stupid to write this, but it's true…using a messaging platform that IS NOT approved for exchanging classified or secret intelligence.
These weren't low-level aides we're talking about. This was Trump's Vice President, his Director of National Intelligence, his National Security Adviser, his Secretary of Defense, his CIA Director and his Chief of Staff. Oh yeah, and the editor of The Atlantic. The fact that these people had this discussion on a commercially available cell phone app is scandal enough. But it's just ONE OF MANY scandals revealed by this fuck-up.
For example, Trump's national security team isn't quite sure if Trump has actually ordered the attack. They were discussing the timing of the attack–when the attack should take place–when Trump's Chief of Staff says, "As I heard it, the president was clear: green light." Seriously, this attack took place when it did because Stephen Miller interpreted some comment from Trump as a 'green light.' Apparently nothing was signed; apparently no official record exists authorizing an attack on a foreign nation. In any normal administration, that would be unthinkable. But this is Trump.
Another thing. One of the members of Trump's national security team, Steve Witkoff, was in Moscow at the time (he's Trump's Ukraine negotiator) meeting with Putin and his people. Let me just say that again. This guy was part of a group chat discussing highly sensitive information involving the military's attack capabilities, using an unapproved app on a cell phone while waiting for a meeting with Vlad Putin IN MOSCOW. In any normal administration, that would be unthinkable. But this is Trump.
There's more. During this astonishingly stupid group chat on a non-secure cell phone, Trump's Director of the Central Intelligence Agency, John Ratcliffe, used the name of an active intelligence officer. He basically outed a working spy, which is a criminal act. In any normal administration, that would not only be unthinkable, but would lead to criminal charges. But this is Trump. His Attorney General and Director of the FBI will almost certainly refuse to investigate the matter, let alone bring criminal charges.

And if that's not scandal enough, when confronted by news media about the incident, Trump said he wasn't aware of it.
"I don't know anything about it. You're telling me about it for the first time."
This is Trump, so that's almost certainly a lie. Almost certainly, also because this is Trump. It's entirely possible his national security team 1) had decided Trump probably intended to order an attack on Yemen and didn't bother to get the decision confirmed, 2) were too lazy or incompetent to use secure communications systems to organize the attack, 3) and when it became public that they'd not only used wildly inappropriate and insecure tech to discuss the attack BUT ALSO INCLUDED A FUCKING CIVILIAN WHO WAS THE EDITOR OF A GODDAMN NEWS MAGAZINE, they decided NOT to tell POTUS that they'd fucked up. Which would mean Trump can't trust his own hand-picked national security team to keep him informed or tell him the truth. Which is entirely possible. Although it's more likely Trump just lied about not knowing, because that's what he does.
In any normal administration, an incident like this would lead to mass resignations and/or terminations as well as criminal charges. But this is Trump.
Right now, it appears the Trump administration is attempting to put the blame for all this on National Security Adviser Mike Waltz, who set up the 'group chat' and accidentally included the editor of The Atlantic. But every single person who participated in the discussion should have known the proper protocol; they should have objected to having the discussion outside a sensitive compartmentalized information facility (SCIF); they should have refused to participate.
What will happen? Who knows? Democrats will be outraged, but will they actually DO anything? Who knows? Will anybody be held accountable for such a colossal fuck-up? Who knows? It's possible that this scandal, like every Trump scandal, will be buried beneath the next cascade of scandal. It's possible nothing at all will happen; nothing will change.
Because this is Trump. Nothing is ordinary anymore. No rules apply, no norms are maintained, no standards exist. There is only Trump and his cadre of trolls, banging around randomly, ignoring actual governance in their pursuit of performative trolling.
