The only way to ever get to the full truth of all that's transpired in the last three years, is to get an outside forensics auditor to go over everything on his own. The outside investigator gets access to everything. There is no reason to believe that the current DOJ has any interest in exposing the truth.
Relying on the DOJ to tie their own noose for the hangman isn't going to work.
You may be right. We are in a war and it will take a stake through the heart to destroy the enemy. To truly win this war, it may require the President explain to the American public in plain terms - the democrat and media coup attempt. He then should initiate martial law and suspend habeas corpus. All suspected subversives in government, media, education, etc., should be arrested and tried in military court.
This or a bloody civil war - I don't think there's any other way to truly drain the swamp.
