The way to strengthen the weakest link is to reduce the number of people destroying it from inside and giving those that work with us the tools to repair it better, so, throw out people that don't belong here due to crimes (actual crimes not a parking ticket or shit like that) or involvement in organizations that are considered problematic. And the way to reduce the number of people of destroying it from the outside is to do better Educational work especially in structural weak regions and settle more people from that weak link there (unless they are at risk for violence, i wouldn't settle gay people in rural Saxony for example...)
