Does undermining the security of women undermine the security of the nation-states in which they live? Micro- and macro-analysis says yes, but ofttimes the causal mechanisms underlying that linkage are left vague. Valerie Hudson, professor of international relations and and director of Program on Women, Peace and Security at Texas A & M, will offer three case studies—abnormal and contrived sex ratios favoring males, brideprice, and polygyny—that show how the subordination and oppression of women produces instability for the nation-state and consequences for international relations.
