Think about it: You would think a president would come into office hoping to spend his political capital trying to accomplish something positive. GW decided to spend his trying to democratize the ME. Foolish goal but ethically laudable - at least initially. Obama spent his trying to get people more health care and it cost his party dearly. Trump could have spent his directly saving people's lives -- how much better could you do that that?
But NOPE, he wasn't having any.
A sad man, a tragic man, and a tragedy for the country.
