All nation-states (all communities really) involves two sorts of obligation: the obligations of the group to the individual (rights) and the obligations of the individual to the group (duties). Liberal democracies tend to foreground the rights of individuals rather than duties, but it is not anti-democratic or illiberal to expect citizens to do their duty as described in the constitution of that community. For some communities, a large well-trained military reserve is essential, and the draft is the best way to achieve that.
