Why on earth would you want to consider someone who has literally zero experience for a cabinet level position?
You say she is "smart, heroic, and beautiful"
Smart- She hasn't done a single thing to show us that, so we have to wait and see.
Heroic- How has she shown that? Merely signing up for the armed forces doesn't make you heroic. She was awarded an Airforce Achievement Medal while stationed stateside, neat, but not what anyone would impressive.
Beautiful- She is hot.
So we are left with "She's hot, lets put her in charge of an important part of the US government". Hard pass.
