So many questions, so much BS....
Here's a brief description of the Dirty War, from Wikipedia. Keep in mind that Wikipedia is heavily left-wing, so their interpretation of things might be backwards of how many of us see it. None the less, here it is:
The Dirty War (Spanish: Época del Proceso or Época de los desaparecidos) is the name used by the military junta or civic-military dictatorship of Argentina (Spanish: dictadura cívico-militar de Argentina) for the period of United States-backed state terrorism[1][2][3] in Argentina[4][5] from 1976 to 1983 as a part of Operation Condor, during which military and security forces and right-wing death squads in the form of the Argentine Anticommunist Alliance (AAA, or Triple A)[6] hunted down any political dissidents and anyone believed to be associated with socialism, left-wing Peronism or the Montoneros movement.[7][8][9][10]Basically the right was appalled by the election of far socialist candidate, and the military sided with them and overthrew the government.About 30,000 people disappeared, of whom many were impossible to report formally due to the nature of state terrorism. The excuse for the Coup d'Etat was the armed actions of the Montoneros and the ERP, but the actual target of the Operation Condor were students, militants, trade unionists, writers, journalists, artists and any citizens suspected to be left-wing activists, including Peronist guerrillas.[11] The "disappeared" (victims kidnapped, tortured and murdered whose bodies were disappeared by the military government) included those thought to be politically or ideologically a threat to the junta even vaguely, or contrary to the neoliberal economic policies dictated by Operation Condor.[7][8][9] They were killed in an attempt by the junta to silence the social and political opposition.[12]
Many members of the junta are currently in prison for crimes against humanity and genocide.[13][14]
It may go the other way here: the Left is on the verge of overthrowing the legally elected government here. Once they have done that then they will start their own version of ideological cleansing: things like rounding up AR-15 owners.
They already use the legal system to punish political opponents, look at the ridiculous prosecutions of Flynn, Papadopolous, Manafort and Roger Stone.
This extends into many city and state legal systems, too, and effects less famous people who interfere with leftist thuggery. As has been pointed out on this thread: two guys got five years for punching back against an antifa mob that *attacked them*. In the Charlottesville riot a young man was sentenced to life in prison for getting into a car accident, again after being attacked by a Leftist antifa mob.
As the brazenness of the Left grows there will eventually be a backlash. (Or, so the theory goes.)
Another great source for understanding what Civil War looks like now is to read some of the work of William S. Lind, who is the person most often associated as the father of the theory of Fourth Generation Warfare, which is what most people familiar with the term feel we are entering into already.
Finally, there is a large body of fiction about what a second civil war might be like. As always, fiction authors can explain things in ways that essayists often can not, and this is certainly true for the broad body of books that take CWII as a major plot element. A list and short synopsis of them can be found on my home page (along with some other things of interest to me).
Including a bit about the Civil War II ping list, which I help manage with a couple other fellows.
Civil War II Ping!
There will be a draft, and huge armies will be raised. If you are over 40 don't worry.
And communications?
