After the United Kingdom and Australasia agreed to Russia's request, the operation to rescue the Russian royal family had essentially succeeded.
As long as there were no further attempts on Nicholas II's life from within Russia, Nicholas II's loyal military would have no problem reaching the Far East safely.
Now that the lives of Nicholas II and his family were no longer in danger, what Arthur was naturally concerned with was the subsequent establishment of the Australasian Empire.
Whether to establish the empire before or after the war, Arthur still had some hesitation.
If the empire were established before the war, it could become more stable after successfully weathering the war.
But if it were established after the war, there would be no opposition from other countries, and the new empire would immediately become the leader among all monarchical countries.
Overall, whether the empire was established before or after the war, there were benefits in each case.
