I'd be surprised if Ukrainians have the slightest trust in 'security guarantees' provided by the Trump regime. Or by European NATO members, for that matter.

Hey Europe, are you planning to copy the US once more, allowing Very Modern Autonomous Taxis in our cities? Think again.

The light rail train on 4th seen passing in front of this roboherd has more passenger capacity than all of them combined.

Russia murdered 7 people in Kyiv last night, and injured 13 others.
Civilian people, who were sleeping in their homes, where they were supposed to be safe, but weren’t, because our neighbor is a terrorist.

1/ Russia sends Drones to scare Europe, known as #ReflexiveControl
The wave of drone incursions into European airspace, attributed to Russia is widely seen as a form of hybrid warfare designed to instill fear, disrupt daily life, and undermine public confidence in European security institutions.

If anything good comes out of the extreme makeover of the original Russian/American surrender proposal for Ukraine, it's of course unlikely that Putin will accept it. Increase the pressure, give Ukraine more military support.

Multiple factors have left the city unprepared for the current drought, including population growth, mismanagement, and sanctions, but a rapidly warming climate is only adding to their problems.

I'm seeing claims that progress was made at #COP30, but it really wasn't. Each passing year with no fossil fuel phaseout comes at great opportunity cost as we further burn through the vanishing carbon budget that remains for averting dangerous warming. See my commentary: michaelmann.net/bad-cop/

Many conclude that #COP30 wasn't a big success, but not a big failure either.
Given the speed with which the climate crisis is developing, any COP that's not a big success is now a big failure, though.
We can't afford losing a year.
