If a hostile country has installed a puppet leader to dismantle your government from the inside, and violent revolution would only expedite your governemnts destruction, how do you combat it?
As long as you're alive, you have options. And the majority of them are usually better than just giving up and dying, either by a civil war or under the occupation forces.
The only thing not clear is the timing. How close is the shit from the fan at any particular moment?
Personally, I'm a big fan of leaving. When shooting, or barbed wires are imminent, just pack your family, some essentials and go have a long boring life somewhere else.
Again - not an option for the majority of people. Not only does that require significant amounts of money, it also assumes the place you're going is accessible (eg open borders, etc) You're advocating from a position of privilege and/or ignorance of you think "just leave" is a reasonable suggestion.
