The Hill is reporting that President Obama has accepted the resignation of General McChrystal and that General Petraeus will replace him in Afghanistan. 

The resignation of General McChrystal is unfortunate, but necessary in light of the Rolling Stone article.  Even if the remarks quoted in the Rolling Stone article were made by his staff and not directly by him, the remarks are still considered insubordination and have to be dealt with.

General Petraeus did a fantastic job in Iraq and hopefully can do the same in Afghanistan.  I know someone who went to high school with him, and she has told me that even then, General Petraeus was respected as a leader. 

It is difficult to change horses in midstream, but if we have to do it, I believe that General Petraeus can step into the job as commander in Afghanistan quite effectively.
