Withdraw from the United Nations
This is a good summary of the latest UN perfidy. I wish that someone could explain to me why the US condones and sanctions such a group, not only by belonging to it, but also by being its primary source of funds?
On the other hand, Elan Journo provides moral arguments for abandoning the UN posthaste, while Mark Steyn takes a closer look at the practical consequences of operating an institution made up largely of dictators and criminals.
(As an aside, it seems to me that for those people who aren't interested in changing the culture at a deeper level, but instead want to take specific political actions, working towards our withdrawal from the UN would be an ideal and invaluable project.)
