depends what you mean by american gov't archives, hell plenty are public accessible openly. But if you're talking about, say, sensitive pentagon documents... then no, the probability of anon intercepting it is more or less none without some serious fucking budget, luck, and stealth. Or an army, lol. Either way, it won't be done remotely, or at least not all of it. it's more complicated than that and I don't know the details obviously but firstly they don't use the internet to store data, more like an intranet. The amount of security measures taken are insane, I forget the specifics (SOME info about security measures were indeed reliably released publicly with the governments permission) but it is to the point where they have something in place to prevent the noise of key strokes being picked up with audio enhancer recordings from a distance outside for the fear that someone could decrypt which keys make which sounds and transcribe anything being typed. The security around the pentagon is intense. I suppose in theory with a crazy budget it MIGHT be possible to develope a receptor that collects photons being emitted from pentagon computers and finds information but I don't think the technology to interpret the data into anything useable currently exists and it could be hard to isolate just the correct source of photons unless you're really close where you will be spotted. The other alternative of course lol is an army strong/big enough to storm the place and steal information. I'm by no means an authority on this kinda thing though so take what I said with a large grain of salt.
