After all the Soviet Union was a permanent member, and China is a permanent member, neither one was/is a place where you or I would want to live. Besides, Colombia, Sudan and Syria have no nuclear weapons. Also funny that you mention Syria, as Syria is currently a member of the council.

Let's look at the some of the current council members and see just who is deciding these weighty issues:

Syria - a state sponsor of terrorism developing WMD
Angola - a failed state
Pakistan - a military dictatorship

Does anyone think that the decision of these countries can lend moral weight to anything?
