It is up to the civilian world to choose polical leaders and heads of state, then live with that choice. Obama is apparently lawfully in office. If there is something wrong in his elevation, it really is up to the Republican leaders to investigate, and their passivity on this issue is noticable. Unlike the general, they are not bound by obedience, indeed, their duty is to question.
