No replies on the holding the door and smiling being the sign of a swindler? That actually sounds like you live in an exceptionally hostile place. I’m swedish, as in people not exactly known for showing a lot of warmth to each other in public, and I always hold the door, and smile at people very often. The smiling part might be somewhat unusual here in Sweden too, but not unusual as in bad or a sign of a swindler. Most people seem to appreciate these behaviors. Either that or I’m absolutely delusional and everyone secretly views me as a swindler ¯\_(ツ)_/¯
I’d say that military bases within European countries is the definition of projecting hard power. If 40 000 soldiers in a military base are called ‘soft power’, what’s hard power then? Nuking the city?
