Progressive taxation can offset the effect of growing inequality.

Here's something we're rarely told growing up: our world rewards wealth, not hard work or talent.

For me, growing up as an activist under an oppressive dictatorship in Uganda, the U.N. was a friend to those of us who fought our way to freedom, as it was for the millions who joined decolonization struggles in the African continent.

The world belongs to the wealthy, and nowhere is this injustice more apparent than in the workplace.

If I took the 40 years of my dad talking to me about war and battles and taking me to battlefields and distilled it down into one question, it would probably be the idea of the necessary or unnecessary war.

When I served on active duty in the United States Air Force, one of my duties was to teach the Law of War.

The Israeli government has proved over the past year its commitment to peace, both in words and deeds. By contrast, the Palestinians are posing preconditions for renewing the diplomatic process in a way they have not done over the course of 16 years.

Some think the worst horrors of war might be avoided by an international agreement not to use atomic bombs. This is a vain hope.
