The correct answer is "Increased death toll and violence of King Philip's War Native Americans' "
The Iroquois were provided with firearms through the Hudson River from the Dutch and English merchants, which reverberated as more casualties in the war, once guns were deadlier than their usual weapons. Iroquois war now had greater tolls, increasing the practice of "Mourning Wars", a technique where the Iroquois took captives of neighboring groups, submitted them into a ritual and then they were adopted to replace the dead Iroquois. The tribe ascended into a war and violence vicious cycle. With the advent of diseases the ferret village was almost completely destroyed in 1650.
There were a couple of reasons for this. First, the Americans were an invading force, and the Vietnamese were fighting on their own soil. Second, the Americans were not willing to make an all-out commitment to win.
The word “imperialism” is widely used as an emotive—and more rarely
as a theoretical—term to denote specific forms of aggressive behavior on
the part of certain states against others; the concept refers primarily
to attempts to establish or retain formal sovereignty over subordinate
political societies, but it is also often equated with the exercise of any form of political control or influence by one political community over another.
