Iranian President Mahmoud Ahmadinejad arrived on Sunday night in Caracas in the first stop of a four-nation tour of Latin America. Besides Venezuela, the Iranian leader will also visit Nicaragua, Ecuador, and Cuba during a week-long tour of the region. Ahmadinejad’s visit comes at a critical time for Iran as it faces the possibility of new sanctions by the European Union over its controversial nuclear program. It is no surprise that the four countries that Ahmadinejad will visit are the most vociferous in their anti-Washington rhetoric and initiatives, particularly Venezuelan President Hugo Chavez and the Castro government in Cuba.
