And it's unlikely as hell that you with your laptop are going to get
acess to any such.

After spending a fair bit of time in advisory groups to the National
Communications System, and the current telecom and advisory groups, I
will point out that if you can defeat the underlying transmission
system, the higher-layer application, often using commercial
transmission facilities, is neutralized.

That's fine for disabling DoD systems, important, but non tactical. I
have a hard time believing that a high-tech invader would rely on US
commercial transmission facilities.


I think we've gotten out of synchronization here. I was referring not to
foreign invaders, but to the hypothetical federal tyranny people
frequently go on about deterring.

If it came to a ground invasion of the continental US, unless the
regulars had totally collapsed, it's rather hard to conceive of any
nation that could take and hold a beachhead -- at least within 30-50
years. The PRC is as good a candidate as any, but they have a long way
before they can pose a significant ampbib threat to Taiwan.
