Though Alex had no way of knowing it, his rival in this arc, aka the MC, had already made his move. Leveraging power and influence to achieve his goals of marrying the first heroine on his radar. While Alex was extremely wealthy, he lacked the power that a monarch had.
Sure, he had his own private army of highly trained hitmen, which he could wield at his authority by commanding his "wife" Selena aka Los Zetas Drug Queen "La Madre." But they were at best a ragtag force of highly trained and well-equipped guerillas.
They lacked the ordinance and machinery to compete assist a nation like Saudi Arabia in a genuine war between Nation States. No, the power Ali wielded as the heir to Oman was significant. And his wealth far outmatched Alex's. At least on paper.
