Your life for Aiur!
You may not be able to buy happiness, but you can certainly buy a superior army. It doesn't really matter how many troops your opponent has, when all it takes to kill them is a massive walking death robot that burns everything it sees with lasers. The more troops are clustered together, the more destruction a well-placed Psionic storm will cause.
You're backing the most sophisticated (and most expensive) army in the galaxy. Why not brag a little? It's not like you can't afford it.
