Should the general offer his resignation?

General McChrystal, CC in Afghanistan, was disrespectful towards the Commander in Chief, President Obama in a RS article. I read the article, and I happen to agree/sympathize with the general 100%. Plus, McChrystal is the black ops of all black ops guys in the Middle East, and diplomacy is not his strong suit. But I was in the military, and I know that he has been insubordinate. I think he should resign (too bad for us). What do you think?
