Bergdahl has not been cleared of all wrong doing. I don't know where you got your information but you need to find more reliable news sources. You need to quite listening to your present news source and start reading the Drudge Report. If you had read the Drudge Report regularly you would know better. Here's the link that will keep you better informed on current events:
DRUDGE REPORT 2014®
If you had read Drudge you would know that Bergdahl was cleared ONLY of misconduct DURING CAPTIVITY subsequent to his desertion; in other words, it was determined that there was insufficient evidence that he assisted the enemy in any way AFTER he deserted. However, whether or not he was a deserter is still to be decided.
There are a lot of links out there that explain that Bergdahl was not cleared of desertion. I really don't know how you missed them all. Here is just one of the many, many links:
“As the Army continues to investigate whether Sgt. Bowe Bergdahl is guilty of deserting his unit, this afternoon they said there is no reason to believe that Bergdahl engaged in any misconduct during his five years in captivity.”
Army Clears Bergdahl of Any Misconduct During Captivity
As for me the evidence of his desertion is beyond a reasonable doubt, in fact beyond the possibility of any doubt. If they find him not guilty of desertion a lot of military men and women are going to be really pissed.
PS: I really would know where you got the idea that Bergdahl was cleared of all charges including desertion. Would you please tell me your source(s).
