Conscription increases the resources available to the military, which militarizes foreign policy. It also makes it tempting to use the larger military, because the resources have already been spent. Other countries tend to feel more threatened by policy disagreements with a militarized state, which further increases the chance that a dispute will escalate to a war. In general, sharp increases in the number of soldiers increases the chance of war within 2 years by 110% (that's a preliminary finding).
In the American context, the people who are most affected by conscription (18-21-year-olds) have a very low voter turnout, and that group is not uniformly against being sent to war anyway. I reran my model to only look at the US. Sharp increases in the size of the military historically increased the chance of the US fighting a war within 2 years by 290% (again, a preliminary finding). For the Fuzzies out there, all the independent variables were lagged several years, so I'm not capturing military increases that are carried out in preparation for an immediate war or an ongoing war.
