On Tuesday's "CNN Newsroom," CNN Military Analyst and former NATO Supreme Allied Commander Gen. Wesley Clark (Ret.) stated that American sanctions against Iran won't be effective in part because "the United States really doesn't want to seal off Iran's oil exports" to keep oil prices from spiking, and the real issue is "will the United States really extend its nuclear guarantee to Israel, and will that be sufficient to keep Iran back from this ring of fire? That's the question. And then, can Israel finish off Hamas in Rafah?"
