I see it this way. Ya want to take over a country. So, create a reason to restrict travel. Create a reason that will make seeing troops in the streets commonplace. Get yer potential troublemakers and put them in camps. Then make them disappear. Announce that the New World Order (which has been talked about for over 100 years now) is in place and if ya don't like it talk to the guy/gal with the tank or APC.

"Good morning, America, how are ya . . .".
