Diplomatic and law-enforcement officials tell The Daily Beast their alarm stems from the arrest of a 22-year-old Army intelligence analyst based in Iraq who has reportedly admitted that he downloaded 260,000 diplomatic cables from government computer networks and was prepared to make them public…

“If he really had access to these cables, we’ve got a terrible situation on our hands,” said an American diplomat. “We’re still trying to figure out what he had access to. A lot of my colleagues overseas are sweating this out, given what those cables may contain.”

He said Manning apparently had special access to cables prepared by diplomats and State Department officials throughout the Middle East regarding the workings of Arab governments and their leaders.
