Firstly i believe that trumps tariff war will be very disadvantage decision for all over the world. In this reason many establishing country could not accept this tariff war in this moment. So i think that it will be very negative effect for all over the wore. Because if we want to following in our country, we can see that our country already face 36% tariff in this time. Which is one of the best difficult for our country. But if we follow in russia, we can see that trump hasn’t any extra tariff in this country. So i think that it was mad genius for trump.
Many countries will retaliate, but only a few (the ones, with good economic situations) will not retaliate. I did not know the USA did not impose tariffs on Russia so I searched and found out why, and also there are a few other countries excluded from the tariffs list due to sanctions on them but still USA imports fertilizers from Russia and did not impose tariffs on them, with an excuse that, they are at war with Ukraine and we won't trade with Russia haha what a Joke.
Well, the motive was to reduce the dependency on foreign products, and increase production within the country, increase employment, but we all know with little loss comes more profit, like in Detroit an industry closed, due to tariffs, 600+ workers are now unemployed, but this little lose, in future will create more, opportunities for these workers, as once the dependency on foreign products will decrease, the production will increase in US based factories, and to meet that they need more workers, maybe better rates, I guess.
