The Soviet Union held elections as well. The point is, when Hitler became chancellor there was no Nazi Germany, no fascist state - he created those over time, and the elections became more and more meaningless. And even if you want to continue to split hairs to keep that point, what of Japan and Germany under the Kaiser? Those were monarchies and they started major wars. The whole premise that democracy leads to large-scale war is one of the more idiotic ones I have seen in some time. If you want a good analysis of the demographic and economic factors that created the major wars of the 20th century, I suggest reading the beginning of Barbara Tuchmans The Guns of August.
