Well put .The threat unfortunately is indeed from inside the country and yes imo the country is on the precipice of determining if it will be socialist/Marxist or ultimately communist.The Marxism (Marx& Engels) playbook being played by BLM/Antifa and the like has taken root with millions of people due to propaganda machines ( mainstream media and mega social media organizations) and the trend to teach socialism principles in many universities in this country for the last two decades.What I mean by Marxist principles/playbook /strategy to turn countries to socialism/Marxism/Communism include : dividing the populace on race,caste/social standing in society,or anything else that would work;attacks on police system ;discrediting the justice system ,create doubt about the governmental Departments and system such as the FBI,Intelligence Departments ;attacks on religion /faith organizations;suppression of any other views other than centralized government being the end all solution to the problems facing the country ;attacks on the military;disarming the populace,and finally redistribution of wealth thru various mechanisms .Unfortunately ,they have been very successful in implementing much of their playbook....just ask those immigrants from Cuba and Venezuela who are in this country how they feel about the events that have unfolded in this country thru the riots and they will/have tellor have told anyone who will listen is those events took place inside their country on the way to Communist Control and loss of freedom to pursue their individual dreams. Unfortunately ,the majority of people in this country have their eyes shut as to what is happening and are unaware of what the consequences will be.By the way Fascism under Hiltler made use of the same playbook ...they just used hate " Jews " as their principle tactic ....Hitler made use of the latest in technology called the " movies " in the 1930's to spread NAZI propaganda. and turn the country ...the rest is history as is Russia,Communist China,Cuba,Venezuela.
The latest election shows how successful the Marxist playbook has become in this country including the depths of what measures taken to steal the election in Atlanta,Philadelphia,Pittsburg,Detroit,Las Vegas.Phoenix,Milwaukee,Minneapolis......there are others but those were the main ones where Democrats were in total charge of the Voting mechanisms including the local courts and Attorney Generals.
I will get off my soapbox now and yield time back to other posters who have different views.
