Should Rumsfeld resign?

Say what you will about the US Armed Forces, but they are a well-trained and phenomenally well-equipped fighting machine. It is also an organization that prides itself on its traditions. In times of war it is these traditions that lend a sense of purpose and continuity to soldiers amidst the uncertainties of conflict. Not the least of the traditions of the Armed Forces is the fact that the uniformed brass unquestioningly follow the orders of their civilian political bosses.

That time-honored tradition is in serious danger of being kicked to the kerb. Six retired Generals according to a Slate story, have gone public with their outspoken criticism of Donald Rumsfeld. Regardless of their First Amendment rights to free speech, it is extremely unseemly for retired officers to speak disparagingly about their ex-boss. It may even be illegal to do so according to this excellent Slate article.

When job-seekers going to their interviews are repeatedly advised to not speak ill of their previous employers, is it too much to expect the same level of decorum from a group of senior military officers, in whose care we had reposed the safety and security of the nation?

For Rumsfeld to resign now, would be to acknowledge and condone the behavior of the generals. This is not to say that the generals did not have valid arguments on their side. It just wasn't their place to voice those arguments.
