It probably tightened a lot of already tight sphincters when it was announced that President Biden had authorized the Ukrainian government to use US-supplied long-range missiles to attack targets on Russian soil:

There was something truly surreal about President Biden suddenly changing course and agreeing to give Ukraine advanced long-range missiles to attack deep inside Russian territory in the last two months of his administration. There was no speech to the nation; no debate in the Senate; just a quiet demonstration of unilateral presidential fuck-you power. You know: the kind we’ve long worried about with Donald Trump. The missiles up the ante considerably against a nuclear power for a simple reason. As Putin noted:

experts are well aware, and the Russian side has repeatedly emphasized this, that it is it is impossible to use such weapons without the direct involvement of military specialists of the countries producing such weapons.

The tiny tsar continued:

We consider ourselves entitled to use our weapons against the military facilities of those countries that allow to use their weapons against our facilities. And in case of escalation of aggressive actions we will respond also decisively and mirrored.

And he looked on edge, bedraggled and belligerent, his arms and hands not moving a millimeter in what sure looks like AI.

There was a time when a NATO missile strike on Russian territory, followed by a Russian threat to attack NATO “military facilities” in response, would have caused the world to stop dead, paralyzed by the fear of nuclear armageddon. Yet here we are, blithely preoccupied by Pete Hegseth’s sexual exploits and Congressional bathrooms.

Others are not so sanguine. “I believe that in 2024 we can absolutely believe that the Third World War has begun,” Ukraine’s former military chief, Valery Zaluzhny, warned yesterday, noting both the new involvement of NATO troops and the involvement of North Korea. Our own president, having brought us much closer to the brink as a lame duck, seemed unconcerned. He was last seen wandering off-stage in the vague direction of the Brazilian rainforest. Not optimal.

The UK prime minister, Keir Starmer, was even punchier, and pledged to allow Ukraine to use British long-range missiles as well: “We need to double down. We need to make sure Ukraine has what is necessary for as long as necessary, because we cannot allow Putin to win this war”. When asked if he was prepared to risk the UK forces or Ukraine or a third country like Poland being nuked in response, as Putin has threatened, Starmer simply ignored the question.

Meanwhile, just to keep things from escalating, the deputy chief of the British defense staff told a parliamentary committee yesterday:

If the British Army was asked to fight tonight, it would fight tonight. I don’t think anybody in this room should be under any illusion that if the Russians invaded Eastern Europe tonight, then we would meet them in that fight.

There seems to be a general impression that Putin is of course bluffing, that NATO can keep lobbing missiles into Russian territory with minimal consequences, and nothing could possibly go wrong.

But Putin has responded by launching a long-range missile that could be used to carry a nuke but didn’t, as well as lowering the bar for the use of nukes in his military “doctrine“. And ask yourself: if Russia were found to have had its own troops assemble a long-range missile and help launch it into the United States, do you think a US president would feel able to let it slide? Here’s what the British missile, the Storm Shadow, did in hitting an underground military facility in Kursk, according to unverified Russia media sources:

[The strike] resulted in the Death of 18 Russian Officers, including a Senior Commander, as well as 3 North Korean Officers. In addition, a Dozen other Soldiers and Officers were Wounded in the Attack, including one of North Korea’s most Senior Generals.

I can’t verify that, but it’s perfectly possible. To have NATO’s fingers on the targeting and launch of that missile puts us in a whole new category of conflict.

The job of a president is to keep us far, far away from any risk of nuclear conflict, as Biden seemed to understand until now. And any student of history will know that blithe complacency as two sides trade military escalations is often exactly the precursor to something going very, very wrong. Accidents happen; misjudgments occur; the point of never getting to this point is that this point contains a host of unknowables, some of them globally existential.

I assume that this is all about strengthening Kyiv’s hand in what will be grueling negotiations to end the conflict once Donald Trump gets back into office. Or the intelligence is worse than we know and it’s about avoiding an Ukraine collapse before Biden leaves office — which, after Afghanistan, would be a final, damning verdict on his foreign policy. Or the intelligence is better than we know and the Russian economy is so weak and his military so depleted that NATO thinks this extra pressure will force Putin to crack. Or it’s a norm-defying attempt from an outgoing administration to derail any peace process the incoming one might want to start. The latter possibility — with Biden rolling the dice because he thinks someone else will have to face the music — is not a minimal risk.
