Is it possible they will try to fight their way out? There's a lot of questions about the number of NG in the capitol. And then Biden said he wanted to go from 25K to 30K, right?
If x% of the soldiers are Chinese loyalists then it's just sheer volume to have so many soldiers per pol. Maybe they're doing the math and realizing they don't have enough. Hence, moar and moar soldiers.
They're all standing there ammo-less too. Perhaps that's another ask to get ammo or get more ammo.
All I know is that this reaction in the capitol is massive overkill. Saw someone opine that it would be cheaper to install Biden as President of Afghanistan than President of the United States at this rate.
