Are We Preparing for Massive Civil War?

We here about a major cleansing in this country. BUT, but, who will do it, God alone, or will it be by way of the wicked finally held accountable for evil by the righteous? Will it be neighbor against neighbor, or a massive number of patriots that say they've had enough? It is apparent that we are so close to completely losing all remnants of freedom and liberty once afforded us by Constitution.
Could the people we think are the good guys, actually be the very ones that turn and rend us?
In Vietnam, we had no front line, we had no idea who the enemy was until they were on top of us. A Viet Cong could cut hair by day and throats by night. Is this how it will be here in America?
Who is, who makes up, who comprises the real enemy that is to be dealt with?
Do Americans wait until it is everlastingly too late to make a difference? We know of two civilizations that warred until no one was left. They both assumed they were in the right.

Will it boil down to this, two enemies, the last ones from both sides losing blood or already dead?

Ether 15:30-32
30 And it came to pass that when Coriantumr had leaned upon his sword, that he rested a little, he smote off the head of Shiz.
31 And it came to pass that after he had smitten off the head of Shiz, that Shiz raised up on his hands and fell; and after that he had struggled for breath, he died.
32 And it came to pass that Coriantumr fell to the earth, and became as if he had no life
