Culture War Roundup for the week of September 14, 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.

So something actually happened regarding Greenland.

Details are fuzzy, but Trump just posted that the US made an agreement with Denmark and Greenland gives the US permanent military control over Greenland, the right to expand its military presence there and, most importantly, to veto any foreign intervention on the island.

This will not make Greenland a part of the United States, which means Mercator Projection dominance lies beyond our grasp for now.

Critics will point out that this doesn't really change anything since the U.S. already had de-facto military control over Greenland. I think in these case the critics would be wrong. If Trump's post is accurate, this does seem substantially different from the previous agreement. It's permanent, the US can expand with Denmark's permission, and they can deny foreign expansion without Denmark's say so.

It's unclear exactly what the US gave up in order to get these concessions, but Trump says it will cost the US taxpayer nothing. Perhaps there are trade concessions?

What's somewhat interesting is that the US barely has a presence on Greenland at all anymore. At one point, in the Cold War, it stationed 10,000 troops there consisting of a quarter of Greenland's population. Today, just 150-200 unlucky souls man the Pituffik Space Base in northern Greenland. Perhaps that's what makes this agreement valuable. The U.S. can now deny adversaries such as China a perch in Greenland without having to actually send in troops.

It's permanent, the US can expand with Denmark's permission, and they can deny foreign expansion without Denmark's say so

Which of these are actually new things that the US was not allowed to do before? Expanding their military presence is something the US could already do. And the presence they had was already permanent. So that is two out of three of your claimed "substantial differences" that seem not so different after all. As for the third, I am not sure that really matters. Unless it allows the US to veto foreign companies, it doesn't prevent the Danes from doing anything they would have actually done in the first place. We would need the explicit details of the deal in order to determine if there is actually anything new here.

Were all of these in writing as the official agreement? Or just de-facto true? It could be that this is Greenland giving us permission to do what we already intended to do in a way that staves off international complaints and lets them save face.

This is the 1951 agreement. As far as I can tell, it gives America the ability to build bases on Greenland and treat them as under American jurisdiction. There seems to be no upper bound on bases or personnel, as long as the areas in question are used for military purposes only and don't interfere with the civilians.

This is why Trump's demands last year seemed so strange. There was no need for a takeover if the goal was to simply defend the place from foreign powers. He could have just sent troops there and rebuild the existing bases from the cold war, or build new bases as needed.

This is why Trump's demands last year seemed so strange.

As much as I'm against the Iran war, it showed there was nothing strange about that at all. Several allied countries refusing to allow American bases on their territory to participate in the assault, clearly shows that a lack sovereignty over the territory where your bases are placed is a huge strategic disadvantage.

Sovereign states have the obligation to prevent their territory being used to attack states they are not at war with. If the deal preserves Danish sovereignty (and both sides have said that it does) then it de jure requires Danish permission for the US to attack third countries out of Greenland. (As all other similar treaties with basing rights do). De facto the US could always ask for forgiveness and not permission, although that is true now anyway.

Sovereign states have the obligation to prevent their territory being used to attack states they are not at war with.

Huh? I'm pretty sure that the European countries that did permit the use of their bases didn't declare war on Iran.

If the deal preserves Danish sovereignty

Whether this deal solves the problem is another question. My point is that contrary to what many people said, there's absolutely nothing strange about Trump / the US wanting sovereign control over Greenland, and "but you're already allowed to build bases" is a terrible argument. If you're actually right about states having a positive obligation to prevent the use of bases on their territory in cases like this, it only strengthens my argument.

Huh? I'm pretty sure that the European countries that did permit the use of their bases didn't declare war on Iran.

Nor did the United States - actual declarations of war are out of fashion nowadays.

The serious point is "Did European and Middle Eastern countries which permitted use of bases on their territory to attack Iran think that this was an act of war?" In the case of the UK, the answer is "Yes" - we didn't allow US use of our bases until we felt there was an appropriate casus belli. (Within the region, Iran considered all countries hosting US bases to be fair game even if the bases were not actively being used to attack Iran, and Starmer announced that this constituted Iran attacking neutral countries allowing the British to act in collective self-defence).

Obviously this is cant and countries were making decisions based on politics, just as a decision about whether America is able to use Greenland to attack third countries in the 2030 War of the Big Stupid will depend on politics and not the text of the treaty.
