"it takes a planet to make life"

FWIW I can recommend Bundeswehrkrankenhaus Berlin, very good urology clinic there. Not sure if there's any chance for you since it's another country, but they're rather accepting and I'd say once there's patient with a life-threatening condition in their emergency they'd rather put them through the CT and into their surgical room rather than waste time. I feel a little shocked that your father is under palliative.

it's exactly this

The way neoliberalism dealt with the public sector including rail service and infrastructure and then come up with "COVID killed Deutsche Bahn" is like saying that poor old sucker who was pushed down the staircase succumbed to his running nose. The problems run much deeper and were already visible in the 70s and 80s, but because it's only the public sector and rail traffic, not about more highways and more cars and then even more cars it never got fixed. Because who needs rails and trains, right.

if you judge driving cars as 'sane', sure; I don't

So if you're interested in Latin you might also find it noteworthy that some object to the translation of the phrase as If you want peace, prepare for war and argue that it was more likely understood as If you want peace, prepare for strife at the time, meaning that the Falcons in Roman politics often did the "so let's send in our boys there to clean up" thing which Rome in fact often did, whereas the Pigeons (doves?) in favor of a diplomatic or otherwise more civil way of conflict resolution found themselves too often in a position where they had to justify themselves and convince the other side with substantial arguments to keep them from exercising the unquestioned default option of the Empire which was, then as now, military intervention.

If nations have legitimacy then they can enter into supra-/international bodies and agreements with legitimacy much like two persons can agree on an arbiter to resolve differences in their mutual contracts. This is nothing new and we've been doing it for a long time—the Egyptian 18th dynasty entered into the first known peace treaty with a foreign nation 1500 years BCE; NATO and the United Nations are modern examples. The US, of course, is a country that has been notoriously difficult to get into international agreements (Paris/Kyoto, WHO, ICC).
