Yes decisions have consequences. The politicians betrayed their citizens and for that they should be sentenced to death via torture: Impalement, dismemberment, etc. The time will come where this will be on the table and openly discussed. They fucked up! Traitors are the lowest of the low and do not deserve to live. But they do deserve a painful death.
I highly doubt that the sheeple will be efficient in stamping out the perpe-traitors. You would have to get rid of the Vatican, Royals, NGOs, mafia, politicians, and all other second hand enforcers. Think of NATO - if you fight you get bombed. You would have to infiltrate all sources of power - there may be sleepers but how many are there?
Also you have to substitute the power vacuum - commoners need a boss they can see and hear.
This is a bit much for a bunch of normies who are passive, unarmed and want to be distracted by the "eternal circus". Women won't help as they only support the power base.
In this kind of situation the disarming of the people is a completely transparent act of taking away the last little tool for defense aginst (government) thugs or other oppressors.
I kinda sense that Incels will be brought up more and more as they are the wild card. It's a standing, decentralized army which may have some intelligent people in it who just want the current system to be abolished... no matter how right or wrong they are they could be a very efficient as they will fight to the death. On top they won't be bought easily - anybody not selling out has to be destroyed as they can't be controlled.
This is thus the main subset of the domestic terrorist- a disgruntled male who sees all of his little world floating into the abyss and seeking revenge. The main reason that the term "Domestic Terrorist" has been established is to dry out any resistence against centralization of power.
