From an after-the-fact perspective, the Second Global War was actually the best, if not the only, opportunity for the Newland Federation to seize global dominance.
According to declassified materials after the war, the leaders of Newland at that time indeed had ambitions.
To put it simply, the Newland leaders attempted to use the strategy from the First Global War, wait for the other Great Powers to fight until they were spent, and then step in to clean up the mess. They aimed to take the opportunity to strike their number one rival, Liangxia Empire, which had rapidly recovered strength during the "20-year truce".
If the path was successful, even if it couldn't completely defeat the Liangxia Empire, it would certainly gain global dominance.
In reality, all the Newland authorities wanted was global supremacy.
Unexpectedly, leading the Liangxia Empire into battle was the greatest politician of that era, and indeed the greatest in the history of Liangxia Empire.
