Iran, Venezuela call U.S. a global danger Amid escalating tensions in the Persian Gulf and a growing diplomatic squabble in the Americas, Iranian President Mahmoud Ahmadinejad received a red carpet welcome in Venezuela Monday as he kicked off a four-nation Latin American tour that is raising concerns in Washington, D.C.Ahmadinejad’s visit, which will also take him to Nicaragua, Cuba and Ecuador, comes a day after the U.S. Department of State confirmed that Venezuela’s consul in Miami was asked to leave the country amid reports that she took part in a 2008 discussion about a potential cyber-attack against the United States.It also comes the same day Iran was accused of stepping up its efforts to enrich uranium, and Iran’s courts announced a former U.S. Marine was condemned to death on spying charges.Calling Ahmadinejad his “real brother,” Venezuelan President Hugo Chávez said the two nations had to stand together against the United States and her allies.“We didn’t ask for this task, but it’s our duty to stop the crazed imperialism that is stronger than ever before,” he said. “It’s a danger to the world — these pretensions of the Yankee Empire to control the globe.”
