Despite all the fuss - especially in the right wing press - I'm still inclined to believe this was relatively low level stuff.
Why? Well, partly because - it WAS easily accessed by a 21 year old kid. And partly because the information itself was floating around out there for MONTHS and the intel community just noticed it.
My job doesn't involve a security clearance, but it does involve private information that I'm sworn to never disclose. It might not pertain to national secrets, but there's an off chance it might involve the taxes and finances of someone's company - and even with THAT, they're pretty tight-lipped about access. They lock up and encrypt everything. Disclosures can result in firing.
The other is how long it's been out there. I don't know a lot about the intel community, but when it's really important, they can usually tell if information has gotten out. This - went completely under the radar. The only thing damning that I saw referenced was that we have about a dozen special forces there - and I suspect if we're giving them air defense systems - that might go without saying.
If it weren't for the fact that this administration lies when the truth would actually suit them better, I'd be inclined to rant about this - but alas, my gut says Biden might be right on this.
