If we can produce for our own needs, if producers prefer the domestic market rather than the export market, perhaps a nation can sufficiently stand on its own feet. Maybe we can be the least affected of all these trade wars.
Kudos to you on what you said here, why will a country that is producing their own things be worried about tariff hikes? The problem here is just that the overdependency on US made products by many nations is getting out of hand, countries should learn to make their own economy better by producing their own needs instead of always looking for importation all the time. If tariffs are hiked by the US and majority of the countries pays less attention to it, believe me, no US government will ever think of doing such a thing like this again in the future.
