How did the Korean and Vietnam War end?

How did it end? Technically, the Korean War did not end. The fighting stopped when North Korea, China and the United States reached an armistice in 1953. But South Korea did not agree to the armistice, and no formal peace treaty was ever signed.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
