The article states that Germany stopping support for Ukraine would be out of the question. I can't see them doing anything even if it turns out it was directly order by the Ukrainian government.
I would seriously consider only having a home phone if I can ever afford to buy a place. Maybe a lightphone or similar to carry that only direct family have the number for in case of emergency.
If you like role-playing games but not so much the combat maybe check out Age of Decadence and Colony Ship by Iron Tower. The combat in those games is intentionally brutal to incentivise thinking ways around it if you can, and I'm pretty sure you can make it through the whole game avoiding combat entirely.
Age of Decadence especially is complete and has many branching paths depending on your build, and Colony Ship is still early access but planning on releasing fully later this year.
The settings are pretty awesome for both, with AoD set in a post apocalyptic land with tech analogous to the late Roman Empire, and Colony Ship being set sometime during a centuries long generation ship voyage.
Yeah I've thought it was the US, or at least US sponsored/advised. The article says apparently the US knew about the attack in advance and told them not to do it, but doesn't give any sources for that that I could see.
