The militaristic faction in Konoha had always proposed conquering other countries, but Haruno Sakura had never agreed, for the issue of population was significant. What use was there in having more territory if it couldn't be managed properly?
Of course, Konoha's top brass needed both the militaristic and the pacifist factions to coexist.
Whenever any group becomes the sole voice, although it may reach the pinnacle of power, it's also the beginning of decay, because no one can guarantee their correctness indefinitely.
Different voices are necessary.
They are supervisory and also cautionary.
Otherwise, Haruno Sakura could have completely replaced the high ranks with her own shadow clones, no one being more efficient than her.
But she did not.
A single person's wisdom is limited, diverse people and their diverse wisdom always enlighten her.
Whether she heeds them is another matter.
