Book excerpt: In these ground-breaking essays, James A. Yunker issues a powerful challenge to conventional thinking on world government. Based on an innovative plan for a limited world government tentatively designated the “Federal Union of Democratic Nations,” this book envisions a legitimate world government a quantum leap beyond the United Nations of today. The Federal Union proposed would operate under some key restraints, such as a dual voting system in the world legislature, and two key reserved rights of the member nations: to withdraw from the Federal Union at their own unilateral discretion, and to maintain independent control over whatever military forces they feel are necessary to their national security. Yunker demonstrates how these restraints would minimize the possibility that the world government would result in such adverse outcomes as global tyranny, bureaucratic overload, or cultural homogenization.
