Few Europeans born after the first part of the 1980s had to do conscription. But Vladimir Putin arrived, ordered an attack on Ukraine and everything blew up.

Suddenly European governments saw how Ukraine needed to mobilize hundreds of thousands of men. Some are beginning to take measures and the main one is to return to mandatory military service for several months, sometimes even longer than a year. The novelty for some countries is that now, unlike decades ago, girls will also have to do military service in some countries.
