Iran and Hamas

Iran is a Shiite nation. Hamas is Sunni. Historically, the two main branches of Islam despise each other and have been very efficient at killing each other. How is it that Iran and Hamas seem to be partners in jihad? What does Iran gain by supporting Hamas? Marc Gerecht of the Wall Street Journal has an excellent analysis of Iran's strategy with Hamas that is eye opening. Let's hope that Obama's teams understand the dangers of trying to open dialogue with terrorist groups.
