The Americans were able to win the war for independence for a number of reasons. First, the British found it difficult to destroy the American armies in the field and simultaneously occupy American cities. Second, they grossly overestimated the extent of loyalist support (or at least loyalist military support), particularly in the South. Third, the war was deeply unpopular at home from the outside, and the Americans always had sympathizers in Parliament who placed significant pressure on a series of ministers to win the war. Fourth, British generals, through incompetence, indecisiveness, and lack of strategic vision, often failed to press their advantages, most notably in the New York campaign of 1776, when Washington's entire army was there for the taking. Fifth, Washington's leadership should not be downplayed. As commander of the Continental Army, he managed to hold the force together, keeping it viable and battle-ready as he led the British through what he called a "war of posts." Basically, although he made many mistakes and never really won a major decisive victory, Washington avoided defeat, making the conflict far longer, messier, and more expensive than the British were willing to bear. Finally, French aid, including French military assistance, proved decisive after 1778, and it is very unlikely the Americans would have been able to achieve independence outright without it.
The Tet Offensive was the turning point of the Vietnam War. On January 1986, seventy thousand Vietnamese soldiers launched a strategic military campaign.
The Nineteenth Amendment to the US Constitution was enacted in 1920, and it prohibited exercising discrimination or denying any US citizen the right to vote due to gender reasons.
It was adopted as the resolution to the suffrage movement that had been conducted by women both at the state and federal levels. In the 1910s many states did not allow women to vote. Until the issuing of this amendment, a decision of the Supreme Court had definitely stated that the Fourteenth Amendment had not granted women the right to vote.
