Part 2 - Different views
Let us begin by comparing what Trump uttered with what his partners said. When Trump and May were asked by a journalist what they think about the flow of immigrants to Europe, Trump brutally and honestly rendered his populist anti-immigrant position: immigrants are a threat to the European way of life; they are destabilizing the safety of our countries and bringing violence and intolerance. So, we should keep them out.
A careful listener could easily notice that Theresa May said exactly the same thing, just in a more diplomatic and "civilized" way: immigrants bring diversity, they contribute to our welfare, but we should carefully check whom we let in. Thus, we received a clear taste of the choice which is more and more the only one presented to us: direct populist barbarism or a more civilized version of the same politics, barbarism with a human face.
Generally, the reactions to Trump from all across the spectrum, including Republicans and Democrats in the US, were one of global shock and awe. Which sometimes bordered on pure panic. We heard how Trump is unreliable and he brings chaos.
For instance, first he reproached Germany for relying on Russian gas and thus becoming vulnerable to NATO's supposed enemy, but days later he praised good relations with Putin.
Then there are his manners: when meeting the queen, he violated the protocol of how you behave in the presence of a monarch! And he doesn't really listen to his democratic partners while being much more open to the charms of Putin, who is nowadays cast as America's big enemy.
