European hesitation to condemn the illegality of USโ€“Israeli strikes on Iran weakens the credibility of Europeโ€™s (entirely justified) legal critique of Russiaโ€™s invasion of Ukraine.

Yes, one can oppose the Iranian regime and still insist international law be applied consistently.

The EU should get serious about maritime security in the Middle East and the Gulf | NUPI To achieve its global maritime ambitions, the EU must strengthen its presence in the Middle East and the Gulf. The current geopolitical climate offers a chance to become a key maritime security provid...

One year ago, I wrote this policy brief for
@nupinytt.bsky.social, arguing for a stronger European maritime footprint from the Red Sea to the Strait of Hormuz.

Today, calls for a sustained European naval presence sound louder than ever.

1/ European defence spending has increased significantly. The real test now is output โ€” how fast and effectively we deliver capabilities.

7/ Europe needs far stronger and more structured knowledge exchange between armed forces and industry on future warfare.

5/ Procurement processes too often separate users from producers โ€” weakening feedback loops and slowing innovation.

It hasnโ€™t received much attention, but Hungaryโ€™s request for a 17,4 billion euros loan under the #SAFE mechanism has recently been suspensed due to risks of corruption.

The country that keeps blocking EU assistance to Ukraine gets a taste of their own medicine.

My colleague Kevin Munger asked me and a bunch of editors to sit and think through AI and peer review. Our take:

We envision an increased (!) involvement of humans in the evaluation of social science.

In plaats van scheuren en plooien, doen de EU-lidstaten er goed aan om het Anti-Coercion Instrument op tafel te leggen in de gesprekken met de Trump administratie.

Tijd om een streep in het zand te trekken.

Trump escaleert het conflict met Europa over Groenland door vanaf 1 februari een extra-tarief van 10 % op te leggen. Maar de aankondiging dat hij (pas) op 1 juni de tarieven zal optrekken tot 25 % wekt de indruk dat hij nog tijd laat - allicht in de hoop dat Europa hierover zal scheuren en plooien.

A European Security Council is long overdue. In a Union of 27, its absence has been a structural weakness.

Hopefully this is the moment it finally takes hold. Fragmentation undermines strategic coherence.

Sending European troops to Greenland under the EU Rapid Deployment Capacity is worth considering, argues @guntramwolff.bsky.social.

Not a bad idea - the EU RDC has been operational since last year.

Curious to learn more about the EU RDC?

The EU has indeed crossed a Rubicon. Enhanced cooperation is a positive development, but its durability remains uncertain. It remains to be seen how it plays out if a large member state comes under eurosceptic leadership.

Given that the financial burden will be borne by 24 member states (excluding CZ, HU, and SK), this hurdle may be manageable.

For these reasons, an optimistic reading of the outcome is justified. That said, there is an important caveat: Joint borrowing backed by EU budget headroom requires amending the 2021โ€“2027 MFF regulation, which still requires unanimity.

Member states have shown a willingness to side-line actors that obstruct the EUโ€™s ability to act decisively in support of Ukraine, effectively side-lining Europe's pro-Kremlin lobby.

Fourth, by invoking Article 20 TEU (enhanced cooperation) and Article 122 TFEU (economic emergencies), the EU is adapting to a reality that requires greater institutional flexibility.

Third, calling the outcome a failure ignores a crucial development: agreement on joint borrowing. This breaks a long-standing taboo and expands the scope for future collective EU action, on Ukraine and beyond.
