I believe that sanctions, tariffs and similar things were more feared in the past years. I remember how people were talking that the USA can dive any country with economic sanctions because it's the most powerful country in the world but recent times showed us that sanctions don't do much, it's very easy to bypass them.
Bro, let's take it one after the other.
The US is a very powerful country, but when it comes to tariffs, the effect is almost mutual, unless the country the US is threatening with tariffs has a deepening economic relationship/reliance on the US. Note that Tariffs are not an economic sanction in most cases. Had it been the US wanted to use its political and economic position to sanction a country, it could have been severe, but the issue of tariffs is different.
Also, a tariff targeted against a country will be more fearful to the country than a tariff that is tyrannically being targeted at virtually all countries of the world (like Trump's). This looks like a joke, and in the end, it is a shared burden that causes countries to look for alternatives. Even at that, many countries would rethink their relationship with the US and realign with the others by reshaping their dependence on the US as much as possible, and we've seen it in many countries now.
This brought me to the last point. Regardless of the position of power the US think it occupies in a trade war, no country has the monopoly of tariff weaponisation, the effect bites both countries, whether in money realised or in scarcity that it would cause in their country, thereby increasing inflation and bringing about other unpleasant chain effects.
