Answer:
War causes a lot of finanicial drainery in the treasury. If this happens then the normal citizens will get affected as they won't get the government facilities they used to get.
War also causes wide unemployment. People will loose their jobs & financial status.
Many able-bodied men are called upon to fight in the war. This will lead to their deaths too.
Also, if these young men die / go to the war, then they won't be able to support their families. The poor families will starve.
If the crop production fails during the war, then there will be a famine leading to the deaths of many as the government during war will be supervising the war activities & not what happens with the ordinary people.
