An NSA becomes a (part of a ) Staasi after the leadership has risen to power basically through murder - murder to the point to where it's impossible to identify the threat any more, for generations. This ignores the relatively sanguine nature of Russian politics in general. You don't get an Ivan the Terrible every day. It's nearly impossible to explain just how bloody the Russian Revolution was ( even if you could cleave it cleanly from WWI, a blood-soaked thing of there ever was ). I don't care how noble and popular a "movement" in the US could be, I do not think the American people will ever tolerate armed insurrection on any scale. I'm also gonna say that while the US is not categorically dictator-proof, it's damned close. If a POTUS used the military while under impeachment proceedings, I'm pretty sure what would happen next. I don't think there's a commander alive that would go along with essentially war crimes under an unstably footed CIC. Never say never, but Congress can pass a resolution and oppose whatever military force POTUS used. I'm pretty sure of which way that would break.
