Lesson in violent takeovers
It seems to me the military controlled government has told the citizens what you need to do to get into power and they have, of course, set the precedent many times in the past 80 years.
A massive show of arms in the streets of all cities needs to be followed by a takeover of all media announcing the country is in a state of emergency. You then get to take control of all institutions, meanwhile arresting all dissenters, even shooting a few to show you mean business.
The constitution is then ripped up, a new one carefully contrived to get exactly what you want in the next 20 years with a clause that also states it's impossible to change it. You have a vote on that charter without ever disclosing what's inside, you arrange and rig an election and then nominate a person who didn't partake in that election as PM. This is the tried and trusted method.
Democracy, elections, peaceful protests, arguments and academic approval of your changes doesn't cut it. Only violent revolution gets what you want. So now we know.
