The problem with this is we are all in different countries with different political systems (and what I am about to say is not aimed at Donald Trump or any other of the world politicians, so don't assume i am attacking anyone's political beliefs)
Politicians are in it for money, fame and a legacy, most/all have no real idea on how things work in the real world and if they stick to 'their principles' it doesn't work as others don't have the same beliefs. We have politicians in charge of departments that have never had anything to do with in either education or work yet they know best on what to do because of their political belief. Politics is based on a belief system and sometimes one works better than the other and vice versa. We have a leader who says something and the opposition will disagree even if it's the right thing and then when in power they change their tune. For true polics to work it would depend on everyone being honest, decent and acceptable to compromise. Whilst we have countries like Russia China and other dictatorships decency cannot work.
None of us truly know what the US President truly thinks or is aiming to achieve, we only have our own beliefs. Things seem to be thrown out to confuse and distract in the same way as we have 'leaks' in government as away of gauging a response without enacting any policy.
If you want to truly understand politics you have to listen to every side with an open mind then you can make the unbiased conclusion,
THEY ARE ALL CLUELESS AND IN IT FOR THEMSELVES.
