I don't know MURACU, didn't her son re-enlist? In any case, the support of most any soldier is implicit, considering they full-well enlist knowing what is within the job description. You agree with every (lawful/ethical) command you will ever be given the moment you place ink on paper. He selflessly sacrificed himself in the aid of his friends and country, without order or obligation. I couldn't agree with Dmorgan statement more.

Sheehan shames her son by using him as a tool to promote her own (likely contrary) agenda; while shaming herself for allowing herself to become and remain a tool of someone elses'.
