Very sorry to know that you're feeling this way. And yes, I think this is a perfectly good place to post this question. A good community should also be there to support its members during times like these. Here are a few things that come to my mind.
Avoid doom-scrolling
Much like for the first few weeks of the pandemic, we all feel the compulsive need to get constant updates on what's happening in Ukraine. But each new tweet or update on The Guardian's live feed doesn't really add much information to your knowledge of the situation. Worse, it can give you the impression that things are continuously worsening while they have only "stably worsened". In this kind of situation, I find it useful to:
- choose one way to be updated on the situation (reading a specific newsletter that I like, listening to a daily podcast in the morning), stick to it, and avoid other low signal-to-noise sources throughout the day.
- favor things that summarize the situation so far, rather than continuously tell me how it's evolving. As a stats-oriented person, I find it more useful to check this forecast on Metaculus every few days, rather than reading every bit of news about nuclear threats.
Take a step back
If you feel overwhelmed, maybe it's also good for a short period to browse EA-related websites a little less. By the very nature of our focus on the long-term future of humanity, we've all been very caught up by the renewed prospect of a nuclear war for the last couple of weeks. And so if you're already seeing it mentioned everywhere in non-EA media, maybe reading in-depth EA analyses on top of that might not be the best thing for you right now.
Accept that you can't really do much
Somewhat relatedly, the EA community focuses on how to do the most good, and how to fix things. And so it's natural for all of us to wonder exactly the same thing now. And while I do think that, on the margin, we can do some things to help steer the discussion in the right direction (e.g. explaining to people why the idea of a No-Fly zone is very bad), it's also important to accept that, right now, the main stakeholders are basically elected officials and army generals, and there isn't that much we can do in the very short term to "solve the situation" like we always try to.
Try to see the bigger picture
By far the most likely outcome is that this crisis will be solved at some point, without any nuclear weapon being fired. And while the geopolitical equilibrium will be different, we'll most likely go back to working on the many other very important problems of the world that we all feel so passionate about. For example, even in the current context, I've personally found the announcement of the FTX Future Fund to be a great source of hope for the future, and I'm very excited to see what it's going to allow the EA community to do in the coming years.
Don't blame yourself for feeling this way
While I don't think this is the end of the world as we know it, it is likely to be a pivotal moment in 21st-century history (akin to 9/11), and what's happening is really pretty horrifying. Especially if, like me, you've never known anything but peace in your part of the World for your entire life. But given that the situation is already bad, you might as well spare yourself the double punishment of feeling bad about the situation and feeling bad about feeling bad.
I find myself seeking out and examining good sources of news and evidence on Ukraine, so I've been following superforecaster and Metaculus estimates about Ukraine a lot lately. Depending on your disposition, this might be bad for mental health, but my investigations have not left me worried about nuclear war.
It strikes me that NATO is rejecting calls to intervene in Ukraine quite strongly, with the chance they will even impose a no-fly zone in Ukraine being only ~5%.
Meanwhile, Putin and his top military planners demonstrated badly impaired judgement. This led them to severe military logistical failures in the early days of the invasion, with some troops confused into thinking they would be greeted as liberators (related: POW speaks), but also to a major underestimate of how strongly the Free World would respond with sanctions. Plus, various corporations are pulling out of Russia. As a result, Russian stocks dropped nearly by half, then rebounded to a drop of about 35% before Russian markets were closed indefinitely.
So, Putin had worse judgement than almost everyone thought, including those expecting him to invade. This could be interpreted as an increased chance that he will use nuclear weapons. But I see it as Putin being severely biased, like my formerly-alive uncle who refused vaccination, rather than being insane. (The difference between these two is that a biased person is more predictable, as long as you have some idea what the biases are; measuring his biases is not easy since he's not honest, but his actions are instructive. Edit: Vlad Vexler is informative about Putin's psychology; here's some key bullet points, though note that since the invasion started, Putin is temporarily more powerful and the regime has gone beyond being just an "informational autocracy"; my sense now is that Putin wants to limit escalation to whatever gets him an appearance of victory domestically—unfortunately, he still overestimates his military powers in Ukraine and it's hard to say how he'll respond to his own failures.) Analysts remain convinced that Putin doesn't want World War 3, so that as long as the free world doesn't provoke him, he won't use WMDs. (He's likely to use horrifying thermobaric weapons, but only against Ukrainian cities.)
Like most Russian soldiers, this war probably took China completely by surprise too. While I'm concerned about China's support for Russia, overall my impression has been that China wants not only to avoid World War 3, but even to avoid secondary sanctions from the U.S. for supporting Russia too heavily. Did you know that China has an agreement with Ukraine to protect them from nuclear aggression? It is likely, then, that their support of Russia will be limited this year, and those who suffer most will be Ukrainians and Russians.
So, the point I want to make is that I don't think World War 3 is likely in the near-term, and neither (it seems) do Metaculus forecasters. The chance of WW3 before 2050 is now estimated at 20%, which is maybe 7% higher than the average probability from 2019 to 2021. Another forecast reports a 92% chance that there will be "No Non-Test Nuclear Detonations" before 2024 (down from 94% through much of 2020-2021).
No evidence I'm aware of indicates an imminent threat of nuclear war, but if you think there is a specific path to nuclear war that is underappreciated, let's maybe discuss that. Of course, even a small chance is scary... but I want to make sure that you're aware that the chance is small.
