The Americans put him into office and this is what he's done. For those that have monitored his campaign rallies, I guess that he's mentioned these tariffs somewhere, right? If not, this is part of his execution and the declaration of another economic war doesn't seem to be a new thing for every newly elected US president that happens.

There's always two sides in it. While the world sees him that he's full of himself and just shifted quickly after months of being elected. The supporters are prolly made themselves frowned because of what he does. But in his belief, what he does is for the good of his people.
