A game of basketball is made up of four quarters, each ten (or in the National Basketball Association 12,) minutes long. At the start of each quarter the team who has the possession arrow pointing towards their hoop gets the ball. Then the arrow is switched, and the next team gets the ball next quarter.
Ending the Vietnam War, 1969â1973. 1  President Richard M. Nixon assumed responsibility for the Vietnam War as he swore the oath of office on January 20, 1969. He knew that ending this war honorably was essential to his success in the presidency.
The Vietnam War may have defined 1960s and 1970s America, but it lasted 10 years by the most widely accepted metric (and, officially, it was never a war at all). And while World War I and II may have killed far more American troops, the fighting didn't linger for a decade and a half.
