Hitler capitalized on economic woes, popular discontent and political infighting to take absolute power in Germany beginning in 1933. Germany's invasion of Poland in 1939 led to the outbreak of World War II, and by 1941 Nazi forces occupied much of Europe.
Hitler took great trouble to make sure that young people were loyal to him and the Nazi Party. He realized that in the future he may have to call on these people to put up with hardships, to fight and perhaps die for him. Therefore, it was important for young people to think that Hitler and the Nazis were the best thing that had ever happened to Germany.
Youngsters were indoctrinated (brainwashed) to think like the Nazis. Textbooks were rewritten to get across the Nazi message. Children were also taught to recognize Jews at a glance.
Lee Harvey Oswald was responsible for killing/shooting John F. Kennedy.
He went to Texas to raise more Democratic Party presidential campaign funds, wanted to begin his little 'quest' for reelection, and because the Kennedy-Johnson ticket just barely won Texas.
I believe it was Great Britain/ England.
