> despite this not making any sense.

Most commentary, for and against, has been exclusively on the economics, and from that perspective it makes little to no sense. But I've seen suggestions in a couple of places that there are relevant "national security" motivations, or to put it bluntly, a greater freedom to wage war - or at least to put oneself in a position where the threat of it would be more realistic. Decoupling the US economy from the rest of the world, but especially from China, makes sense if the strategic cost-benefit analysis sees a significant potential for war with that country. It's a commonplace of international relations, and intuitively obvious, that the more integrated are the economies of two countries, the less likely they are to start wars with each other (no doubt there are exceptions, but as a rule...). That doesn't have to mean anything imminent or indicate concrete plans on the part of US, but it's plausibly a factor in the overall calculations.

In fact, the economic interdependence of the US and China had seemed to be a big reason to remain hopeful that there wouldn't be a war between them, among other reasons of course. Reducing this interdependence seems to destabilize this situation. The unfortunate fact is that I can't see the US military establishment just peacefully allowing China to become more militarily powerful than itself. I'd be happy to hear other perspectives on this, I'm far from an expert and haven't seen this angle discussed much.

This is indeed a common way of thinking and intuitively obvious but I think it has also been proven wrong by the war in Ukraine. We sanctioned Russia as hard as we could and it 3 years later they're still there.

Withholding some nebulous service industry from a country that's mostly reliant on primary and/or manufacturing is probably not a strong enough deterrent to a sufficiently motivated political force. It might be that it just puts service industry reliant countries at a disadvantage.

Drone warfare is another piece of the puzzle, both how they are employed in the Ukrainian war as well as in the red sea blockade. The west is also at a disadvantage here compared to, say, China. When was the last time you saw a drone-dragon lightshow outside of Shenzhen?

We thought we had world peace through commerce but it was probably an illusion. I think everyone is rethinking the last 150 years of history right now.


Just as a matter of logic, you can't prove wrong a rule of thumb that admits exceptions by pointing to an exception. There can always be reasons why, despite economic integration, other factors take precedence, e.g. perceived existential risks can push countries into war despite foreseen economic shocks.

In the case of Russia, while there were subtantial sanctions, it was still trading natural gas to the EU, and I believe they still are. China and India also helped Russia (and themselves) tremendously by buying huge quantities of discounted hydrocarbons, and I think it's plausible that there were indications before the war that such deals would be available.

As an aside about drones, a striking number of new companies established over the last handful of years in several European countries are military drone specialists. By now it's quite obvious why. In the future I guess there'll be a new slew of companies specializing in counter-drone tech.


I don't disagree, but you're just explaining why it doesn't work.


> the strategic cost-benefit analysis

Is there anything pointing to this supposed thorough analysis really being done behind the doors? Genuinely asking, because for now in my opinion from POTUS communications I don’t make me think there is and this comment is another instance of trying to make something irrational rational.


No specific evidence, just that the State department and the analysis branches of various agencies still exist and are staffed by professionals whose job it is to conduct such analyses. It's not out of the question that some of these might have filtered up and in some way influence decisions.

If the tariffs remain in place then one result that is guaranteed is that they will reduce trade between the US and the rest of the world, and reduce the most with the most tariffed countries. Whether that's rational or irrational I guess is the question I'm asking, and I'm looking for reasoned opinions either way


Trump has talked about his tariff idea since the 80s, and talked to Oprah about it way back when we lived in a completely different world. I'm not sure his 80s era plan is based on 2025 dynamics that somehow filtered up to him in his first months of office.


Fair point. It's reasonable to conclude that a lot of the impetus is coming from Trump himself. On the other hand, the Biden admin quietly kept Trump's first-term China tariffs, even though they reversed many other Trump policies. So that suggests some involvement of the wider foreign policy establishment that's continuous over changing administrations


Or just shows that anti-China sentiment is politically popular in the U.S.


I think the strategic angle is important, but I doubt it's part of a long-term plan to start a war with China. I think the more likely concern is that if the US becomes too dependent on Chinese manufacturing, China could impose sanctions on the US to control US foreign policy.

And a similar concern applies if the US lacks the manufacturing capability to wage wars with its own resources. Something we already saw that when we ran out of ammo because of the war in Ukraine.


Thanks, that's probably a more sober and probable assessment. It could make sense for reducing potential Chinese leverage over US. I think if the point were to shore up defense-critical industries, though, then direct support for those industries would make more sense and be considerably less disruptive than these tariffs.
