I would say that you are absolutely correct on this point.
The central problem that we face is that we have far too many people in our own Government who actively support our enemies. We also have too many people in the general population who will tolerate such behavior or even support it. It is unfashionable to point out the effective remedies to that sort of problem.
At a minimum, traitors should be expelled from any position of authority. A selective hardening is necessary (and it won't be tolerant of the Leftists) We still may have enough left of the "Rule-of-Law" that we can change our Government peacefully.
If not, then our enemies will change things for us.
Don’t forget to include the subversive Mainstream News / Entertainment Media, and their associated cabals of Marxist sycophants. They have all but single-handily brought us to this point - and I don’t believe it an exaggeration to state such as being the case.
