Those in power where others depend on their continued incumbency are rarely told the truth. They live in a bubble of flattery and lies and lose touch with any reality they might once have had. Dictators cannot be challenged as they will kill the critics and/or threaten the critics' families so they live in a complete fantasy world but it happens, I observe, to a lesser degree where the fleas live off the dog.
Trumpo has been long associated with narcissistic tendencies and now he has power a-plenty. However, as with Obama, the presidential authority only runs so far before it meets checks and balances as can be seen already in legal challenges and street protest.
If you look at the list of countries from which Trump has banned unchecked immigration you can see a seismic difference in the level of freedom between these rogue states and free, democratic America. Trump is not ISIS, nor Al-Shabab. He has never thrown anyone off a building for being gay or put a man in a cage and burned him to death for the cameras. It is these horrors he is trying to resist, albeit hamfistedly.
That is not to say I support Trump's actions. I don't think 'torture works' and it is also immoral and he has said some awful things about women.
