The campers, some clad in combat fatigues, carefully aim their assault rifles. Their instructor offers advice: Don’t think of your target as a human being. So when these boys and girls shoot, they will shoot to kill. Most are in their teens, but some are as young as 8 years old. They are at a camp created by one of Ukraine’s radical nationalist groups, hidden in a forest in the west of the country, that was visited by the Associated Press. The camp has two purposes: to train children to defend their country from Russians and their sympathizers — and to spread nationalist ideology. It is important to inculcate the nation’s youth with nationalist thought, so they can battle Vladimir Putin’s Russia as well as “challenges that could completely destroy” European civilization. Among those challenges: LGBT rights, which lecturers denounce as a sign of Western decadence.
