Answer:
The Soviet Union and the U.S. were primarily responsible for the Cold War because they were the two biggest superpowers of their respective government and economic types. The United States was the best Capitalistic and Democratic country, while the Soviet Union was a Communist government. This led to proxy wars between the two, most notably the Vietnam War.
French and Indian war (also known as the seven years war), led tensions between the 13 colonies and Britian. This is because in this war france lost New France to the British. When taxes began to rise in the colonies and Americans were starting to rebel, French were happy to help since it would be a sort of revenge since losing their colony in North America.
The Supremacy Clause (Article 6, Clause two) declares that the Constitution is the "supreme law of the land". It establishes that federal laws rule over state laws. This ensures that there will be no disagreement between the state and the national government over who has more authority. Federalism is a system of government where the power is shared between the state and national government, but this does not mean that they are equal. The national government will be "supreme".
