The AP reports:
At this huge oil field in southwest Iran, one building stands out among the pumps and maze of pipelines: On its roof in giant letters, big enough for satellites or pilots to see, are the words: "We can do it."
It was the catchphrase of Ayatollah Ruhollah Khomeini, though it does have the familiar ring of a slogan used by another, contemporary politician. I kind of preferred Help is on the Way!
