The correct answer to this open question is the following.
We are talking about the Gulf of Tonkin Resolution. This resolution changed the rules of war as outlined in the U.S. constitution. With this resolution, the US Congress granted the President of the United States -in this case, Lyndon B. Jhonson- unlimited powers to stop communism in Vietnam. After the aggression of two US navy vessels stationed in the Gulf of Tonkin, Congress passed the resolution on August 7, 1964. From this point on, the US Army committed to total support of South Vietnam in the Vietnam War.
<span>B) Pre-war alliances were made in secret and elevated diplomatic tensions within those governments.
Or sometimes the fact that alliances were being made was announced publicly -- but the negotiations about the alliances were conducted behind closed doors. And often the terms of the alliances were kept secret, so that only the parties involved knew the full details. This contributed to an attitude of escalating nervousness and tension as the nations of Europe maneuvered for strength over against their perceived adversaries.

Conditions before the Industrial Revolution were terrible. Child mortality was high and the children who survived, barely had enough to eat. You see, because of The Little Ice Age, agriculture was terrible. And before the revolution, most of Europe was agriculture based. The lack of food made people stunted and killed many. The food that could be harvested, were taxed and there was almost no profit.
