Sorry, but I think people being critical of the US system and saying that's the fault of the system are wrong.
The problem is when someone comes along and acts in a brash way that ignores those cheques and balances as irrelevant anyway that the problem occurs.
With the best will in the world, once Trump started on the Campaign trail and got support behind him all 'norms' went out the window.
It is the norms that keep people restrained, not the institutions.
In redrawing the norms, Trump has a free hand. He can act outside norms, and anyone using the norms against him is instantly painted as the traitor rather than him.
Do not think it won't happen here. It has been stopped once by Gina Miller, but the attack is on going and not going away.
Its the norms and accepted views and behaviour within society that are the important thing that are the constraint not the institutions.
In the intervening period of transition from democracy to dictatorship the trick is to create confusion so institutions are slow to act, confused and toothless. That's what is happening. The institutions actually mean that people put their trust where they shouldn't because they have false notions of security and protection from tyranny.
Once those norms are broken you can use the institutions AGAINST the people through fear. Hence 'national security'.
Trump says what needs to be true to justify what happens next. That's the language of fascism.
A language that is spoken widely in the UK by media and respected individuals who hold office.
It WILL happen here. Do not assume it won't.
Do not assume Gina Miller has saved us. She merely put the brakes on.
