Donald Trump's speech to the United Nations was one of the clearest expositions of the way he sees the world, his ideology in its rawest form.

To his supporters, it will be seen as Trumpism unplugged - to his critics, Trumpism unhinged.

Over almost an hour, he took aim at his opponents and their ideas, picking them off one by one as he toured the world. He began at home, praising the United States and himself. He said the US was living through a golden age and repeated his much-disputed claim that he had personally ended seven wars, something he argued merited a Nobel Peace Prize.
