Hmm.. to be pedantic then i dont think megalomaniac fits Deus. So far he has not shown an obsessive wish for power.
Nor the desire to become the immortal god-king. I also cant see why he would want that. It sounds excessively dull compared to just being the advisor to the king.

And i also dont think its fitting to call them unrestrained wars.
Actually it seems surgical, or minimal aggression is more fitting. Since Deus has employed such an overwhelming degree of force and supers he could afford to use the kid gloves on his opponents.

Else yeah it does seem like Deus can already show an impressive degree of progress in his pocket state.
Max has confirmed the investments in infrastructure.
