( CNN) The United States was born in a rebellion against the totalitarianism of King George III. The Constitution was designed to prevent tyranny through a system of checks and balances, but in President Trump's America, those precautions are failing.

Donald Trump holds the grandiose notion that only he should rule America. Unchecked by cowed or complicit Republicans in Congress, Trump invokes executive authority to alter policies and practices long established by law and pact.

Days after his summit meeting with Vladimir Putin , no one knows what the two tyrants agreed to, or even talked about — not the President's top aides , nor the Pentagon , nor security establishment or Congress, never mind the rest of us. And in the midst of the ensuing commotion, Trump has invited Putin to Washington, without telling his top intelligence official and no doubt most other key aides and officials.
