They know exactly what they're doing. They have never once even accidentally done the right thing, none of this is random. It's a coordinated assault by the global oligarchy with Russia leading the charge.
They intend to destroy the USA as a global power.
They intend us to die in uneducated filthy misery.
They don't care if the county is a smoking crater as long as they get to own the crater and lord it over the rest of us.
