Moscow warns the U.S. about 'clash of civilizations'

Moscow urges the United States to avoid escalating tensions around Iran over its nuclear program as it could lead to a "clash of civilizations," the Foreign Ministry said Tuesday. The Russian ministry said the Iran crisis could have devastating consequences for relations between "civilizations," and then the U.S. would have to prove it is not preparing for a "clash of civilizations" by building up "Fortress America," separated from the rest of the world by two oceans and strict border controls.
