"Sir, moving an army into foreign soil would spark a diplomatic crisis," Reginald cautioned, his voice laced with concern. "The Valorians might view it as an act of aggression, which could lead to unforeseen consequences. We don't know enough about their capabilities."
"And I believe that the Kingdom of Zambesi is not in any way affiliated with the Valorians. So even if we enter the army into Zambesi, they won't react unless they aren't civil. But there is still a problem, Your Highness. We need justification on why we are sending our army into Zambesi. Only the Military High Command can issue that order even if you advise it," Reginald reasoned.
"That is exactly why we need a casus belli. The tribe of the Matabele," Prince Theodore began. "They are an oppressed minority in the Kingdom of Zambesi vying for autonomy. We will position ourselves as their protectors. This will give us the perfect pretext to enter Zambesi under the guise of a humanitarian intervention."
