When registering a country code domain, keep in mind where the domain is being registered. A shift in government or geopolitics can have serious consequences.
I think the point is politics in a nation can change at any time, and as such you may lose the domain/no longer feel safe supporting that nation. Just because they wouldn’t now doesn’t mean they wouldn’t in the future. (Especially with how well AfD is polling and how much CDU/CSU seem to be starting to cooperate)
