Retired Virginia Army Colonel sues woman accusing him of rape; How do you think this will play out for him?

A retired Army colonel from Alexandria is suing one of his classmates from West Point during the 1980's, claiming her recent allegations of a rape from 30 years ago cost him a military promotion. Earlier this year Col Riggins filed a multi-million dollar defamation lawsuit against his former classmate, saying her claims of rape on what some consider a radical blog (Social Media), cost him a promotion to general in the United States Army. Do you think the Secretary of the Army's decision to pull Col Riggins' name from the promotion list was appropriate even though a review board ultimately decided Col Riggins was "fully qualified for promotion? Do you think the unsubstantiated past allegation, rehashed via social media site, should have been allowed to play an integral part in the decision making aspect of his career? Do you think her actions to post this on her site 30 years later were in response to learning that he was up for promotion? And, considering this is a touchy subject, please be thoughtful and respectful with your responses. Thank you! :)
