A current issue in the news is the concern over the nuclear program in Iran. There are fears that if Iran obtains (or seriously attempts to obtain) nuclear weapons the situation would become a new Iraq or that the nuclear technology would be given to terrorists by the Iranians or that Iran would use the nuclear weapons on the US or Israel.
This issue of course has relevance to economics through the application of game theory. This first article is a post by Tyler Cowen that discusses his relative optimism that nuclear weapons would not be used if obtained by Iran. This article is by Thomas Schelling, who as you remember, won this past year's Nobel prize in part for his work on the application of game theory to nuclear deterrence. Each article remains optimistic about the situation using past evidence of nuclear weapons not being used, particularly with Israel, India, and Pakistan.
Both articles are very interesting and give a further example of the application of economic thinking to current important problems.
