Culture War Roundup for the week of April 6, 2026

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

One possible negative consequence of the Iran war that I haven't seen talked about much is that it might encourage both the American establishment and the American public to think too lightly of war with China. More the latter than the former, really - I am sure that the former at least understand the danger of nuclear war and have no interest in getting personally hit by nuclear weapons. But even they might become a bit too reckless as a result of these easy military victories. Meanwhile, the vast majority of the public has very little understanding of military affairs and probably don't really understand the difference in power between China and every other US rival. The way I would put it, the Iran war is like an NBA team playing a college team, maybe even a high school team. Yes, Iran is keeping the Strait of Hormuz closed and are pulling off the occasional successful strike against Israel and the Gulf countries. But that is happening because they are lucky in terms of geography to be sitting next to one of the world's most economically important waterways and are also right next to the Gulf countries. In terms of pure military-on-military action, the US military is dominating while suffering barely a scratch.

War against China would be like an NBA team playing another NBA team, maybe a weaker NBA team but an NBA team nonetheless. There is a danger of insufficient caution causing a series of minor escalations to blossom into full-scale war against China.

The Persian war, our battle of Carrhae, is giving China pause about its Taiwan invasion plans if it has any brains. If Iran can close the straight of Hormuz then Japan can close the south China sea.

The Persian war, our battle of Carrhae

Okay, let's not get over-excited.

Unless the Chinese leaders are total idiots, I think they probably realized many years ago that effective closure of all of their sea-going trade routes is a likely outcome of an attempt to invade Taiwan. So I doubt that the Iran war has changed their calculus in that regard. I'm sure that they have been very busy analyzing the war to get other kinds of information, though.

I don't know if China has any serious intention of attempting to grab Taiwan, but certainly they have plans drawn up for how to go about it if they do decide to try. My guess is that, unless they are total idiots, they have baked in the assumption that they will lose most or all sea-going trade for the duration of the war, and they might be banking on the assumption that their industrial might will compel countries to trade with them again after the war concludes. Not all countries, but at least enough countries that the invasion may end up having been worthwhile.

If I were the Chinese leaders, though, I probably wouldn't try an invasion regardless of how the Iran war is going. There is just not enough possible gain given the risk.

No, not really. Does Japan have a network of defensive and offensive emplacements that had been put in place over decades? Do they have a massive indigenous drone program that does not rely on foreign imports? As a society, are they tightly integrated into the global economy (and hence dependent upon foreign imports) or are they mostly self sufficient? Is their primary foe on the other side of the world with an anemic manufacturing base, or is it directly adjacent to them and with a huge domestic manufacturing base? In another world, Japan could close the south China sea without any problems - but not in this one.

Japan could probably mine the SCS pretty easily with their fleet of submarines, which might close it to international traffic based on the risk profiles we've seen.

They have a pretty large submarine fleet incidentally, nearly as many AIP submarines as China does, and a competitive production rate.

This does nothing to change their position - Japan is far more dependent upon sea-based imports than China, and any kind of escalation will result in them hurting themselves far more than they hurt China. If China was somehow completely cut off from the sea, they'd still have access to extensive land-based trade networks, including Russian fossil fuel supplies. If Japan is cut off from sea-based trade, which China would be able to do far more easily, they have no other options.

Yes, it's absolutely true that Japan versus China wouldn't be much of a contest.

But note that part of the Chinese situation is that they are locked "behind the first island chain" which creates chokepoints. Japan doesn't have the same weakness because their back is to the Pacific.
