War and human life have been coupled since before antiquity. Ares, the Greek god of war, wielding fist and sword, battled with immortals and mortals alike. In more recent times, as economies and politics become increasingly interdependent--or globalized--Janus, the Roman deity of doorways and passageways, who watched in two directions at once, has begun to take center stage, looking at both international stability and security. This study examines globalization from the perspectives of three interlocking stakes: international military and commercial investment; dual-use technologies; and export control.
