Putin is helping Iran.

Zelenskyy is helping us.

Trump does not seem to understand or is ignoring these basic facts.

Hope someone on his team will help the president correct this policy position and...

Thank Zelenskyy.
Arm Ukraine.
Sanction Putin.

Why is Trump negotiating when Europe pays for everything and he’s a terrible negotiator acting in bad faith?

Hi all. Before our rapid rollercoaster descent into the economic abyss (?) let me remind you that not all computer science tools are AI, and many of them don't cost much to be useful. So please don't give up hope.

Now buckle up and enjoy the ride. πŸ₯΄

What could go wrong has already gone wrong.

The UK has 150 universities, many of them excellent in applied research. Only a set of donkeys would outsource their research whilst having those facilities in their back yard. But that is exactly what has happened here.

The Netherlands is trying to draw a line under a year of chaos with fresh elections – will it work? Prime Minister Dick Schoof called fresh elections following the first collapse of his government, which would go on to fall a second time within a few months.

The one post I could find on Blue Sky about Selma van der Perre.

She visited the Dutch school in London every year to share her incredible story and meet the children. Her last visit was only a few weeks ago.

May she rest in peace. ❀️

Citing the worrying poll, but not the papers debunking it. Perhaps a wrong choice?

Dear community, last time you helped us reach lots of new BlueSky followers. Now that we see that there is an exodus on X, it is important that these people can also find us on BlueSky for all necessary updates about Ukraine.

Would you like to share this message, preferably with a quote? Thanks!
