My thinking is that the honest brokers in the Spygate Affair - and this includes President Trump - are afraid that if they start mass arrests of Leftist traitors - the blow back from the Left may be an insurrection - a massive nationwide rebellion that may lead to civil war.
Yes, I also think in time this country will explode into a Second U.S. Civil War. no matter what actions or non-actions the powers that be take in the Trump Administration.
Appeasement never works....Today the Administration makes a sort of dishonorable peace treaty with the Left by not prosecuting the high ranking traitors like Hillary Clinton and hopes thereby to avoid the civil war.
But sometimes war is inevitable - and when outcome of elections are not accepted by one side - the countdown to the ultra violence of civil war has begun.
You make a lot of good points...
