Plumbing was more of a luxury/comfort for people that also made their life easier. Baths were common and were usually taken while standing up in public baths. Bathing was also used for ceremonial purposes in religious services and rituals. Toilets were only limited to those who could afford them, so the upper class. Lower classes used urns or sump pots. Upper class toilets were stacked bricks with a hole that would drain out. Plumbing on the 2nd floor though was led by pipes to the streets. Limestone was used to prevent leakage.

Vietnam "hawks" or supporters of the war wanted to see Communism defeated. The war with Vietnam provided an opportunity to contain and possibly destroy Communism. They supported an "any means necessary" approach to defeat Vietnamese aggression which pulled us into war.
