Well it's positive for various countries that benefit from an end to US dominance over the world. :p

So for the US itself? The theory would be that the tariffs will increase US manufacturing sector. But the cold hard truth is that it isn't the 1830s anymore and last time tariffs were tried happened to line up exactly with the Great Depression.

Even an competent administration would have great difficulty making tariffs to restore manufacturing work in the US, if that is even at all possible. It fails because other countries just put the same tariffs back on the US.

So with the Trump's administration some kinda of serious economy meltdown is almost certainly the result.
