The left is doing all of these things.
The cabal who control Biden and the Democrat Party fully intend to destroy the USA.
That is their objective.
They consider the USA to be an evil, racist, nazi nation which should be destroyed, must be destroyed, and will be destroyed.
To weaken the USA sufficiently to allow it to be dominated--perhaps conquered--by a hostile foreign power is part of their plan, but their ultimate plan is the complete destruction of the USA.
Understand this, and everything falls into place.
The greatest danger is that this reality is beyond the belief, imagination, and comprehension of millions of Americans, who are the useful idiots of the cabal.
