What was kennedy's new frontier? how was that philosophy played out, both domestically and internationally, within the first few years of kennedy's administration?

During the 1960 presidential election, Jonh F. Kennedy used the slogan 'new frontier' to describe his political goals and ambitions. 

Domestically, under this slogan he introduced social reforms and tax cuts. He started off the space program, initiating the space race, but also made efforts to improve the relations with Russia. 

On an international level, the most consequential event was the invasion of Vietnam which Kenedy authorized. He also established the Peace Corps with the purpose of spreading American culture abroad.
