Arthur didn't care about how the British Empire and Italy were vying to win over Hungary. After all, Hungary was far from Australasia, and it didn't matter who controlled it, as long as it wasn't under the control of Soviet Russia.
The splitting of the royal financial group made Arthur realise one thing, which is, "biggest" doesn't always mean "best".

At any time, a monarch should understand the importance of checks and balances of power.
No matter how immense the Royal Security Intelligence Agency may be, if it is the only intelligence agency in Australasia, there is a potential for a variety of problems.
Upon careful consideration, Arthur decided to split the Royal Security Intelligence Agency into three different intelligence departments, each with different duties.
