A second shot at a PhD
I have an unexpected and exciting professional news to share
o.simardcasanova.net
Despite having completed 90% of the manuscript, I was never able to defend my PhD
It's definitely unexpected, but I'm thrilled to announce that I have restarted working on a PhD
You can read about what happened and my plans on my newsletter: o.simardcasanova.net/p/8e29c3...

If you had told me a year ago that retired French military officers would be talking to press about fighting Americans to defend Greenland before I turned 35, I would have assumed you were talking about the 0.0001% chance timeline.

I’m European policymaker adjacent and the publicly acceptable way for me to say this is that my views about European strategic autonomy and the role of Europe as a superpower have radically, and probably permanently, shifted since Trump attacked Venezuela
It amazes me that so-called "serious folk" in the US are failing to realise that the next two generations of European policymakers are going to be incredibly more inclined towards anti-Americanism than any generation since the interwar era.
Folks in the US still like to treat the whole Greenland invasion stuff as sufficiently unserious to engage with, but it is sufficiently serious that NATO allies are actively deploying tripwire forces to deter the US. That is *already* a political and actual cost to them, and to US relationships

I don’t think the words in this post have ever been written until now and yet
More Americans should be made aware that France’s nukes have been designed to kill more or less 100 million Russians and making them able to kill 100 million Americans would simply require reprogramming new targets
Also, France could theoretically deters the United States just on its own thanks to its nukes

“The Europeans won’t fight back” is a wildly factually incorrect statement and shows an astonishing lack of understanding of 1) how the geopolitics of escalation works 2) how Europe works 3) how war works
France is a nuclear power and is deploying troops in Greenland, for God’s sake

If Trump invades Greenland, the Europeans won't fight back, Republicans will defend it, Democrats will issue statements, there will be protests, and most Americans will disapprove of it enough to earn Democrats a bit more of the vote in November. Then on to the next thing.
More than an attempted coup, where a mob tried to seize Congress on live television did? There's not going to be an implosion about anything. It's either a slow slide towards oblivion where everything gets incrementally worse as people try to live normally, or a slow grind in the opposite direction.

This. Greenland defense is a tripwire—putting various European countries’ personnel in harms way in an attempt to deter attack—not an effort to win a war with the US.
A real Europe-US war would destroy the world. The goal is to not have one. Which was more than accomplished by a robust NATO. Alas.

Finding the reactions to this bleakly funny. Lads, the point isn’t that you are sending enough people to “win”, because we in fact, can’t win. It is just to have a tripwire! If you are going “why not 13, like Germany?” you have not understood how bad things are.

Denmark is underway to move more troops to Greenland in cooperation with undisclosed allies.
Preparatory staff are in place to solve logistics for potential larger Danish forces.
Details are sparse but dr.dk reports that first plane landed 2 days ago.
