From Holden:

I understand the military’s need to prevent the enemy from receiving any information that might give them an advantage. And I hope that concern is what drives the Army’s efforts to censor bloggers within the ranks, such as Army Capt. Eric Magnell’s Dagger JAG and Army Spc. Colby Buzzell’s My War.

However, I find myself agreeing with this statement:

“I really think it has much less to do with operational security and classified secrets and more to do with American politics and how the war is seen by a public that is getting increasingly shaky about the overall venture,” says Michael O’Hanlon, a senior fellow at the Brookings Institution in Washington.

This post by Colby Buzzell indicates to me that he agrees with O’Hanlon’s assessment, too.
