Just in case there will be any good reason for me to visit the US and CBP wants to know whether I should be allowed to be in the US. The US is a fascist country, and Trump is a crazy wannabe king who belongs in prison. Neither Ukraine nor Denmark land and people belong to crazy fascists.

The EU should introduce a plan to increase tariffs on all US services. Not a stupid "the King said tomorrow you will be charged with new tariffs," but a long-term plan that makes investing in EU companies profitable over time and doesn't immediately disrupt the market.

Some people don't learn... they will be looking for "a balance with russia" under the rubbles of Berlin. They can't even understand their own history. Europe and the US didn't find a balance with Nazi Germany. Nazi Germany had to be destroyed, invaded, and denazified.
🇩🇪 Merz: Russia is European country, our largest neighbor.
If we succeed, in the longer term, in once again finding a balance with Russia—if peace prevails, if freedom is guaranteed—if we succeed in all of this, then the EU, and we in Germany, will have passed another major test. I wish this for us.

I've moved the mini wind turbine into my office so it can sit in the background during calls…
Turns out it's quite the distraction. "What's that?!" 😅
It's currently showing the live output at Gwynt y Mor wind farm just off the North Wales coast.

Red carpet for Putin in 2025 = absolute lack of moral values. Utterly disgusting (and dangerous for the world). Doesn't matter it's Trump, Modi or anyone else. Doesn't matter what "what about" or economic or political arguments you have. Lack of moral values + "what about" = lack of moral values.

A report user doesn't understand non-additive calculations, so you change the measure total to be additive, disregarding the statistical and business meaning.
The last step on this slippery road is saying, without a gram of sarcasm, "Mr. Trump, you're the most stable genius in the universe".
