The fact that they haven't leads me to believe their case against him isn't quite as airtight as you believe.
I'm not sure whether he's broken any US laws or not. He did not, after all, leak the information, he merely publicised it after someone else (Bradley Manning, apparently) leaked it. Wikipedia mentions no warrants out for his arrest apart from the rape one, for which he's apparently right now "under arrest in absentia" in Sweden.
Bradley Manning, of course, remains in solitary at Quantico pending court martial -- he most certainly broke some laws.
